How to Buy Veterinary Digital X-ray Equipment without Experiencing Buyer's Remorse

Have you ever bought something and regretted the purchase?

I think I have at one time or another. However, it’s one thing to regret ordering a cheeseburger and fries, but quite another when I regret buying a $50,000 car or truck.

When I make a big purchase, I want to feel good about my decision. I want to make sure that I made the right choice.

I want you to feel great about buying from me! I understand it is no small thing for a Veterinarian to spend $20,000 or $30,000 on digital x-ray equipment, and I want you to feel great about buying from us.

So, here is my “purchase without buyer's remorse” plan:

The 30-day satisfaction guarantee, or your money-back offer. When you make a digital x-ray system purchase, I will give you 30 days so that you feel comfortable and confident that you made the right choice.

And if you are not satisfied, return your digital x-ray equipment for a full refund.

Yes, that is correct! A FULL refund!!

I know that after the vet digital x-ray equipment is installed in your clinic, and once you learn how to use the software, you will be very happy with the results you get.

I can offer this guarantee because I am very confident with the quality of the digital x-ray equipment we sell, and I want you to be completely satisfied.

Here is the fine print:

• Equipment must be returned in original packaging.

• Equipment cannot be returned if damaged by the user during your 30 days.

• The buyer pays the cost of shipping/packing/insurance of all returned equipment.

• You must give us a reasonable chance to correct any dissatisfaction.

The main reason I am offering this “30-day satisfaction guarantee or your money back” is to give you peace of mind.

I understand I’m not as big as Idexx, Cuattro, or Sound-Eklin. Perhaps that makes you think twice about trying us out.

But I am confident that our equipment is as good, if not better, and now we have a “30-day satisfaction guarantee or your money back” - which the big boys do not offer!

The bottom line is simple:

• I am offering quality digital x-ray equipment for the veterinary industry at an amazing price, with a great warranty, and now a 30-day guarantee.

• I want to do the right thing, treat you with respect, and help you be successful in your veterinary practice.

What to Know About the Mindray Vetus E7 Ultrasound

Purchasing a new veterinary ultrasound machine is an exciting, yet complex, decision. A veterinarian may feel overwhelmed by choices. There are many systems available at all different price points, with different features—many of which are hard to compare side by side for vets who are new to performing ultrasounds.

In this article, we’ll look at some of the features of the Mindray Vetus E7 Ultrasound, a veterinary-specific model, to see if it might be a fit for your practice.

What Is the Mindray Vetus E7 Ultrasound?

The Vetus E7 is a laptop-type portable ultrasound unit made specifically for veterinary practitioners. It’s designed for use on both small and large animals, for abdominal studies, cardiology, musculoskeletal and small parts studies, and even some reproductive applications.

This 2022 model features a lot of new and advanced technology. Some of the key features that might appeal to a veterinarian are discussed below.

Features of the Vetus E7

While every practice has unique needs, these features may be beneficial to veterinarians in many clinical settings…

• Small size and portability. The Vetus E7 is a laptop design, so it can be transported as needed. There is a 15.6-inch, high-resolution color LED monitor. The unit is 1.7 inches thick and weighs 3.0 kg (6.6 lbs) without the battery and 3.5 kg (7.7 lbs) with the battery. Battery life is about 1.5 hours on the laptop alone, or up to 8 hours with the included U-bank battery.

• Durability and ease of cleaning. The unit is basically “sealed” in, making it more difficult for liquids and stray hairs to get inside the unit or under the buttons. This includes an anti-liquid touchpad that replaces the standard rollerball, and seamless keys/buttons. Materials are said to be durable and chemical resistant. It stands to reason that the seamless design might also be helpful for protecting the unit from dust and humidity when out in the field.

• ZONE Sonography Technology+ (ZST+). This is the first laptop-based system to use the technology, which is supposed to provide excellent image clarity and quality. A simplified way to describe this technology would be to say that it uses software to process acoustic data in large “zones” at a fast speed. This large amount of acoustic data creates a detailed image and can help reduce tissue motion artifacts. Dynamic pixel focusing means good special resolution and the ability to focus at various depths without the user needing to manually adjust the focal point. 

• Dedicated veterinary presets and user-friendly workflow. Presets are available according to species (canine, feline, equine, bovine, ovine, and customizable), and further subdivided by body size (including dog ranges of <5 kg, 5-15 kg, and >15 kg). The iWorks feature offers smart scanning protocols that standardize the workflow and allow automatic addition of annotations, marks, and measurements. The company claims this can reduce exam time by 50% and reduce keystrokes by 80%, for faster and more efficient studies. 

• iScanhelper, a built-in learning tool that provides tips on how to scan, as well as anatomical illustrations, patient positioning and probe placement pictures, and ultrasound images for comparison with real-time scanning. 

Additionally, the Vetus E7 system includes many standard features such as Doppler and compatibility with image storage software. 

Conclusion

Is the Vetus E7 right for your veterinary practice? It depends on exactly what you’re looking for, what your practice plans to budget, and what you plan to use the machine for, i.e., what’s the return on investment based on the expected number and types of studies that would be performed at your practice.

Also, it’s important to ask your supplier questions to ensure you know exactly what you are purchasing. Check how many probes are included (and which types), whether there’s a warranty and what it covers, and anything else you might want to know. See if it’s possible to get a demo, too.

All that being said, the Mindray Vetus E7 does offer some exciting features for veterinarians. In addition to the practical considerations that make it easier to keep the machine clean, many vets would appreciate the features that may make it easier to learn and use this ultrasound unit, such as intuitive workflows and processing capabilities for high-quality images at multiple depths. 

It’s common knowledge that ultrasound can require a lot of training and practice before a vet feels confident in the modality. So, anything that makes the process a little easier or more intuitive, and helps with obtaining high-quality images, can certainly be a plus.

Can Veterinary Technicians Perform Ultrasounds?

With the growing demand for veterinary services—and many vet hospitals being fully booked—many vets are delegating tasks to skilled veterinary technicians when possible. But is an ultrasound something that can be delegated to vet techs?

Here, we’ll cover what separates the duties of a veterinarian and a veterinary technician, and how that applies to performing ultrasounds on companion animals.

Which Duties Can a Vet Tech Legally Perform?

Credentialing, as well as the laws and rules governing what veterinary technicians can or cannot do, vary widely from state to state. So, it’s important to check your state’s rules and regulations for specifics.

However, as a general overview, trained technicians are allowed to perform many of the same duties that veterinarians perform. But they must operate under the supervision of a licensed veterinarian.

There are a few things that vet techs aren’t legally able to do, though. This includes making a diagnosis, prescribing treatments and diagnostic tests, performing surgery, and giving a prognosis.

How Do a Vet Tech’s Training and Legal Restrictions Apply to Performing an Ultrasound?

With the above rules in mind, think about what’s involved in an ultrasound study.

The person performing the study must be familiar with the ultrasound machine and how to use the controls to operate it. They must know how to find the organs/anatomic structures of interest and take the correct views (images and videos) of those structures, along with any relevant measurements. 

So far, all of these tasks are something a vet tech could learn how to do. 

Although it can take time to learn and practice ultrasound technique, vet techs are smart and educated, and capable of doing many of the challenging tasks a veterinary hospital requires on a daily basis. 

So, given the right training and opportunities to hone their skills, it stands to reason that many vet techs could be taught to perform ultrasound studies.

What About Interpreting the Images?

The tricky part comes in when it’s time to interpret the images or videos that were captured during an ultrasound study. 

Even though a highly trained and experienced vet tech will probably understand the significance of what they are seeing on an ultrasound study, there are legal limitations to what a vet tech can do with that information.

Interpreting the images would involve making a diagnosis (or at least a diagnostic rule out list) and possibly giving a prognosis. Plus, based on that information, prescribing treatments or additional diagnostic tests (such as performing an FNA or obtaining a biopsy) could be the next step. 

Those things would fall into the realm of services limited to a licensed veterinarian.

So, a vet tech could perform the ultrasound study and capture images. But it would be up to a veterinarian to interpret the study.

In many ways, this is very similar to how x-ray studies are already performed in veterinary medicine. It’s also similar to the way ultrasound techs operate in human medicine. 

So, it’s not a stretch to imagine a similar system could work for ultrasound studies in vet med.

Potential Pitfalls to Consider

With ultrasound studies, there is value in someone being able to interpret the studies in real-time.

For example, if a mass is noted in the liver, a veterinarian might recommend an FNA of the mass. However, a vet tech wouldn’t necessarily be able to prescribe this next step.

Also, certain findings may require veterinary knowledge to put into context and alter the course of the scan. One example is finding a splenic mass, which might prompt a veterinarian to also look and see if a right atrial mass is present. 

One solution is to have veterinarians present (or at least be accessible for questions) during the study. That way, additional views, and procedures could be performed as needed. 

However, even veterinarians who are new to ultrasound themselves may run into shortcomings with image interpretation. So, there may be limitations no matter who is performing the study, until a person gains years of practice.

A good place to start is to have whoever is performing the study—whether it’s a vet or a vet tech—use a standardized list of views to obtain. Then those views can be sent to a specialist for interpretation, which will help everyone learn.

Training and hands-on practice are also crucial. Skills will need to improve over time.

Does It Make Sense for Veterinary Technicians to Perform Ultrasounds?

With veterinary practices being so busy since the pandemic, it makes sense to utilize staff (veterinarians, techs, CSRs, and the rest of the team) to their full potential.

This is one reason why the discussion of a mid-level practitioner (veterinary nurse practitioner) role has become more prominent.

Giving additional roles and responsibilities to educated, trained vet techs could carry a lot of benefits. One would be to take some of the time-consuming duties off the doctors.

This could improve the overall efficiency and profitability of the practice by freeing up more time for the vets and allowing them to see more patients or perform more medical procedures.

Additionally, new roles and skills for vet techs could provide much-needed pay increases, job satisfaction, and career advancement opportunities.

While performing ultrasound studies isn’t a full solution to these industry-wide concerns, it’s one example of a skill set that could contribute to the expanding role of technicians in the profession.

Each vet practice must decide what will work best in their individual practice and adhere to the laws of their state. But there are many reasons to believe that vet techs learning to perform ultrasounds could be beneficial to the whole practice.

5 Tips to Improve Proficiency With Ultrasound

By becoming proficient at ultrasound studies, a veterinarian can elevate patient care at their practice while also boosting profits.

Whether you’re evaluating the abdomen, the heart, or something else, an ultrasound study can be a very valuable tool.

Here are five ways for a practitioner to improve their ultrasound skills and offer more of this valuable service to pet owners…

The Right Equipment Can Make a Vet’s Job Easier

Having good, well-functioning equipment can really make life easier for a veterinarian and their team. 

This could include a variety of factors, such as…

• Does all of the ultrasound equipment—probe, machine and monitor, and any programs for saving videos and information—work? Does any component (or the whole system) need to be repaired or replaced?

• Is the equipment of a good quality? Maybe it’s technically working, but do the images you produce have enough detail and clarity to see what you need to see? Is any part of the process cumbersome, which can make it less likely that the ultrasound will be used to its full capacity and potential?

• Would routine maintenance or an upgrade improve efficiency and make it easier to offer this service to clients and their pets?

This is all-important because even as you learn, practice, and improve your skills, inefficient or subpar equipment may make it challenging to fully implement your new training and may lead to frustration.

Standard Protocols and Techniques Can Improve Efficiency

If an ultrasound is only performed once in a while, it may feel like a hassle or lead to confusion or inefficiency when trying to schedule and perform an ultrasound study.

To improve efficiency and make it easier to offer ultrasound services at your practice, consider all stages of the process, including…

• Has the veterinary team been trained and empowered in all aspects of scheduling an ultrasound study? For example, is there a specific day of the week, especially if there is only one doctor at the practice who performs ultrasounds? Has enough time been scheduled, especially if sedation is needed? Having a standard set of instructions or protocols can help the team and make things run smoother for everyone.

• If the patient needs any special instructions to prepare for their ultrasound study (such as fasting from the previous evening), is there a clear process for communicating this to the client?

• Does the veterinary team know all the tools you would prefer to have available during an ultrasound study? This may include everything from a v-trough, towel, and clippers, to syringes and microscope slides in case an FNA is indicated. Having a kit or list prepared ahead of time will help save time so no one has to run to the other room and grab supplies mid-study.

• If a patient is sedated or under anesthesia, is there a standard format/form for monitoring?

• Is there a report prepared for the client? Can video clips or still images be saved as part of the medical record? Will the client be present during the ultrasound in some cases? Make sure the whole team knows what should be done.

Take Advantage of All the Resources You Find Helpful

This may include textbooks and other references for what is normal on each ultrasound study and what is not. 

Access to a second opinion can also be helpful. Consider discussing your findings with colleagues within the practice, subscribing to an online forum such as the Veterinary Information Network (VIN), or even using a specialist consultation service for an expert, second set of eyes on your ultrasound images or videos.

Practice Makes Perfect

Any new skill can be challenging at the beginning. But ultrasound proficiency will improve over time, with practice. So even if fitting more ultrasounds into a busy schedule feels time-consuming at first, it will probably get to be second nature over time. 

In addition to training and courses, it may help to ultrasound healthy patients for practice, to gain a thorough understanding of all the different ways normal anatomy can look in different sizes and breeds of veterinary patients. This could be done with the pets of veterinary team members, or possibly offered to clients at a discounted price in the early stages.

Communicate Effectively With Clients

If pet owners are unsure about proceeding with ultrasound for any reason or experiencing sticker shock, the conversation can take up a lot of time for veterinarians and their team members. By planning what to say and gaining comfort with these conversations, time can be saved while providing patients with the care they need. 

Efficient conversations about pet ultrasounds may include general principles for good communication (active listening, empathy, non-verbal communication, etc.), as well as explaining the excellent value that clients are receiving for the cost. For example, explain just how much information can be gathered from an abdominal ultrasound study. In addition to looking at suspected abnormalities, it’s a thorough look at many important organs. Occasionally, unexpected issues are caught early, or if the dog or cat is normal then the owner can have peace of mind.

Putting all these principles together, a veterinary team may find the whole ultrasound process becomes more efficient. This is good for team morale, as it helps to keep the day running as smoothly as possible. It can also increase a practice’s bottom line while providing excellent care for patients.

For all these reasons, it may be well worth it for a veterinary team to invest time and effort in adding ultrasound to their practice!

Ultrasound of the Duodenum and Jejunum in Dogs and Cats

There are many reasons why a veterinarian may perform an ultrasound of the duodenum and jejunum sections of the small intestines in a dog or a cat.

For example, the vet may suspect a GI foreign body, inflammatory disease, or neoplasia. 

Here are a few key checkpoints to remember when scanning the duodenum and jejunum.

Setting Up the Gastrointestinal Ultrasound Study

If a patient can be fasted, that’s ideal.

An empty gastrointestinal tract may be easier to visualize, whereas food or digestive content may cause artifacts such as beam attenuation. However, this won’t be possible for all patients, especially in an emergency situation.

Patients are often placed in dorsal recumbency, although lateral recumbency may also be used. The patient can also be repositioned mid-study if needed for better visualization. 

Performing a Thorough Evaluation

Often, a GI ultrasound study is part of an entire abdominal study. In some cases, the GI tract may be visualized on its own. Either way, to ensure nothing is missed, it’s important to perform the study the same way each time. Many experts recommend keeping it simple by following the GI tract in its normal order of digestion, i.e. starting with the stomach, then moving on to the small intestines (duodenum, jejunum, ileum), cecum, and colon. Examine each segment in both longitudinal and transverse views.

Evaluation should include wall thickness (and whether that thickness remains uniform within each GI section), wall layers, luminal contents, signs of obstruction, the presence of a GI mass or multiple masses, infiltrative disease, and whether there’s normal motility/peristalsis.

The Duodenum

The duodenum is located along the right lateral abdominal wall in dogs. It can be found near (ventral to or ventrolateral to) the right kidney. The cranial portion may be challenging to see and may require viewing via an intercostal approach.

In cats, the duodenum may be closer to midline, or just right of midline.

The wall of the duodenum is up to 5mm thick in dogs, and 2-2.5mm thick in cats.

Jejunum

It’s often difficult to trace the long jejunum loop by loop. So, most veterinarians evaluate the jejunum by sweeping the transducer from side to side across the abdomen, in a cranial to caudal direction. Slightly overlapping each sweep will ensure that nothing is missed.

The wall of the jejunum is 2-5mm in dogs, and 2-2.5mm in cats. 

Evaluating the Layers of the Intestinal Walls

The walls of the intestinal tract have 5 specific layers, in this order: the luminal-mucosal interface (most interior layer), mucosa, submucosa, muscularis, and serosa (outermost layer). 

In longitudinal view, these layers are easily distinguished from one another (in a normal patient), thanks to their alternating pattern of hyper- and hypoechogenicity. The inner and outermost layers, and the submucosa, are hyperechoic. The mucosa and muscularis are hypoechoic. 

If these 5 layers are not distinctly visible throughout the intestines, it could indicate a problem. For example, focal wall thickening with obliteration of the layers could indicate focal neoplasia.

Make notes of any wall thickenings, whether they’re focal or diffuse, and whether the 5 layers are still distinguishable or not.

One normal finding that could be mistaken for abnormal is Peyer’s patches (pseudoulcers) in dogs, which appear as focal, hyperechoic indentations within the hypoechoic mucosal layer.

Signs of Obstruction

Sometimes, the obstructing foreign body may be visualized directly. However, this is often not possible. So, a foreign body obstruction may be detected due to differences in intestinal dilation proximal and distal to the point of obstruction. The intestinal tract proximal to the obstruction would tend to be dilated with fluid and gas, while the distal intestinal tract is normal or even empty.

With a linear foreign body, plication of the intestines may be seen via ultrasound. The foreign body itself may or may not be well visualized.

In case of an intussusception, the affected section of intestines will have a characteristic “bullseye” appearance in transverse view. If this is noted in an older pet, be sure to search for signs of neoplasia that could explain why the intussusception occurred.

Intestines may be hypermotile with a recent obstruction, but possibly hypomotile with a more chronic condition.

GI Neoplasia and Inflammatory Conditions

Neoplasia in the digestive tract may occur as a solitary mass, multiple masses, or diffusely as an infiltrative disease.

As mentioned above, discreet masses are often identified because of their focal thickness relative to the rest of the intestines and disruption of the wall layers.

Infiltrative disease, however, can be more difficult to pinpoint. There may be wall thickening with or without disruption of the wall layers. In particular, it can be challenging or impossible to differentiate between small cell lymphoma and inflammatory bowel disease in cats without further testing.

Regional lymph nodes should be evaluated, too.

Conclusion

The duodenum and jejunum are an important part of any GI evaluation. It’s helpful to get an idea of what’s normal and what’s not for these sections of the small intestines, as they’re commonly evaluated for a variety of conditions, including those listed above.

Equipment Options for Your New Veterinary Practice

If you’re ready to take the leap and open the veterinary practice of your dreams—or if you’re still exploring options and seeing if practice ownership is right for you—finding the veterinary equipment you need is an important part of the process.

After all, it’s difficult to diagnose and treat patients without the proper tools.

Depending on the type of practice you open, your equipment wish list may include…

• X-ray and ultrasound machines.

• In-house bloodwork analyzers.

• Surgical lights, an autoclave, and anesthesia monitoring equipment.

• IV pumps.

• Exam room tables.

• Kennels.

• A scale to weigh patients.

• A tonometer for measuring intra-ocular pressures.

• A dental cleaning unit.

• Computers, and veterinary clinic software.

• Credit card processors for payments.

• A washer and dryer.

• Separate refrigerators for medications and for your staff to keep their lunches in, and a freezer for cadavers.

• Specialty equipment, such as a vehicle for a mobile practice, and pneumatic drills, and an MRI for a neurology practice.

Plus, there are smaller items to consider, like otoscopes, blood pressure cuffs, staff uniforms, and all your daily supplies like needles, syringes, and gloves.

With all this in mind, it’s not surprising that your equipment costs could add up to tens of thousands of dollars—or more—making your equipment a vital consideration when opening and financing a veterinary practice.

Not to worry, though, because you do have options.

Considerations for Purchasing Veterinary Equipment

Purchasing new equipment is certainly an option many practice owners pursue. It’s exciting to get the latest technology delivered to your practice’s door, and—depending on the type of equipment—installed by experts. And, the equipment should be in excellent condition because it’s brand new.

When buying new, it’s important to do your research, though. Be sure you’re getting good quality and the best value for your dollar. 

Also, check the manufacturer’s or seller’s warranty—because there would be nothing worse than investing your money only to have a malfunction (less likely with new equipment, but possible) or have something get dropped or broken during the grind of daily practice.

And finally, ask about support and training. For example, who do you call when you have a question about the machine? And, does the company offer training to your staff, to ensure the equipment is used to its maximum potential?

Purchasing used veterinary equipment can also be an excellent option. Many machines are designed to last for years, and your colleagues may want to sell relatively new equipment in order to upgrade. This can be a great benefit to you because you can catch a real bargain.

For used equipment, we recommend usedvetequipment.com, a site exclusive to veterinary professionals looking to buy or sell veterinary equipment, with guidance on shipping and a moderator for payments. But, you may find quality used equipment through other online sellers or medical equipment specialist resellers, too.

With used equipment, inquire about the condition. Also, ask if there is a warranty still in place—you don’t want to miss out if it is still in place and transferrable.

Finally, consider maintenance costs with any equipment you buy. Maintenance is crucial for keeping your equipment running for as many years as possible, potentially saving you lots of money in the long run if you can avoid replacing your machines sooner than necessary. So, these maintenance costs should be factored into your budget.

Financing for Veterinary Equipment

If you have some cash saved up, you may be able to purchase some of your equipment outright. But, chances are you’ll need to finance at least some of your purchases.

For financing new equipment, check with the manufacturer to see if they allow payments over time. Some may have monthly payment plans. These plans take away some of your initial financial pressure since the money you bring in with the equipment can fund the monthly payment (for example, your x-ray fees can support your monthly payments for a good quality x-ray machine). 

Alternatively, you could seek financing from a bank or other lender. The bank you’re working with on practice financing may include equipment costs as part of your loan, or as a separate negotiation. Or, you may reach out to another lender.

Typically, lenders refer to these loans for equipment as “capital leases,” and they may offer monthly payment plans. 

The lender would own your equipment until the loan is paid in full, but there’s usually an affordable (as low as $1 for some institutions) purchase option for you once you finish all the loan payments.

When evaluating a lender or other equipment payment plan, here are some things to look for…

• What’s the interest rate?

• What fees are associated with the loan?

• What is the loan’s term, or how long will you be paying?

• Is there a purchase option once the loan is paid in full, and how much it will cost?

• What penalties exist for late payments, paying off the loan early, or if you would like to get out of the lease?

• The reputability of your lender (if it’s not the lender you’re already working with, do they have recommendations from the equipment sales representative or other veterinarians? Do they routinely work with veterinarians?).

Also, talk to a tax professional to find out if the depreciation and interest payments on your veterinary equipment are tax-deductible.

Your Overall Financial Picture

Before purchasing any equipment, it’s important to think through what the equipment will do for your patients, and what sort of return on investment you can expect. 

For example, will you use the equipment often, or will it only be on rare occasions?

What training is required to learn how to use this equipment? What about client education on the benefit of the service? How many years is the equipment expected to perform?

A veterinary consultant, or financial professional who’s familiar with veterinary businesses, can guide you through these analyses and include these considerations in your business plan so your new practice can find the right balance of initial equipment purchases, then grow and thrive over time.

Get The “Whole Picture” For GI Foreign Bodies

Sometimes, Foreign Bodies In A Pet’s Stomach Or Intestines Are Obvious On X-Ray Images—For Example, A Bright White Metallic Object, Or A Whopping Big Children’s Dinosaur Toy.

However, sometimes GI foreign bodies and obstructions are trickier to detect…

For example, certain fabric objects—like socks or pieces of a blanket—don’t show up well on radiographs.

Here’s a quick guideline for how to get the “whole picture” and diagnose GI foreign bodies with confidence…

Clinical Evaluation

If you suspect a foreign object in the stomach or intestines, there’s a good chance the patient presented to you with symptoms—may be protracted vomiting with a full obstruction, or milder GI upset if there’s an object in the stomach that’s not digestible but also not causing an obstruction yet.

You proceed by taking a thorough history from the owner and then performing a physical exam.

Then, based on your findings, you perform radiographs.

Radiographs

Be sure to take orthogonal views to get as much information as possible about the dog or cat’s digestive tract.

For some patients, this may be enough information to give you a clear answer. Maybe you see obvious signs of an intestinal blockage, such as plications or extreme fluid and gas retention that doesn’t move over time. Or, maybe you see a mineral-dense rock or other radiopaque objects.

If you don’t have an obvious answer, there are some additional tactics you can pursue, including…

• Repeating the radiographs later for comparison, if the patient is healthy enough to wait.

• Performing a barium contrast study. This is a good option for many patients, but something you may wish to avoid if the patient is vomiting a lot, due to the risk of barium aspiration.

• Performing an ultrasound evaluation. This is a quick and non-invasive way to get more information but may require a waiting period or referral if you don’t have an ultrasound in-house.

• Performing abdominal exploratory surgery. This may give you a definitive answer and allow you to treat right away if a foreign body is present, but is obviously more invasive and requires a thorough discussion with the client to set up expectations.

Ultrasound

An ultrasound is a great way to gain additional information about your patient’s digestive tract, and it can work hand-in-hand with x-rays.

Now that your radiographs have given you a good overview, the ultrasound allows you to “zoom in” on the finer detail of soft tissue structures.

For example, if there’s a radiolucent cloth or foam children’s toy stuck in the intestines, the ultrasound can help you locate and characterize the obstruction.

These additional details may help you decide what to do next, and determine whether or not the patient needs surgery.

If you don’t have an ultrasound in-house, you may need to refer to a specialist or emergency center, and there may be a short waiting period if you use a mobile ultrasonographer.

By having an ultrasound in-house, and gaining the training and confidence to use it, you can potentially have your answers sooner—for more peace of mind for you, and the ability to provide faster answers to your worried client.

Treatment

Based on your findings, you’ll use your clinical judgment to decide the next step—whether that’s surgery right away or a period of observation and supportive care followed by a recheck and a repeat of your images.

As you know, some GI foreign bodies are harder to diagnose than others…

However, the more tools you have in your toolbelt, the easier it is for you to make timely decisions about the best care for your patients.

Ultrasound Techniques: Evaluating the GI Tract

An abdominal ultrasound is a tool that can help you with visualizing and diagnosing a variety of conditions in your canine and feline patients.

Today, we’ll be talking about evaluating the gastrointestinal tract.

Depending on your patient, you may be doing an ultrasound exam of the stomach, small intestines, and colon to look for…

• Inflammation and wall thickening

• Foreign bodies

• Neoplasia

• Pyloric outflow obstructions

• Intussusceptions

• Enlarged mesenteric lymph nodes

This isn’t an exhaustive list…

But basically, if the patient is having GI symptoms and your x-rays haven’t provided the answer you need, an ultrasound is often a good next step.

That’s because it provides more details about tissue structure in real-time, as opposed to just the silhouette of radiographs. Often, x-rays and ultrasound work well together.

It may take a little bit of practice, but with experience you can catch on to ultrasound technique and do your ultrasound exams in-house rather than referring.

Here are a few tips for getting the diagnostic information you need during a simple ultrasound evaluation of the GI tract…

• If possible, have the patient fast beforehand. That way, you can get a clear picture of the GI tract without a lot of food or fecal matter to block your view of certain structures or create artefacts such as shadowing. You can also consider an enema if needed.

• Position the patient. Dorsal recumbency is most common, although lateral recumbency may also be used, especially for visualization of deeper structures. Use a trough for comfort, and if appropriate consider sedation (most patients don’t need to be sedated, though).

• Experts recommend having a systematic approach to look at the entire abdomen. Whichever viewing order works best for you, it’s good to be consistent so nothing is forgotten. And, the GI tract will be an important part of your evaluation.

• Choose a machine and probe that work best for your needs, then practice and develop comfort using the different settings, especially adjusting depth and gain (brightness). That way, you can focus on seeing what you want to see, rather than fussing with settings during your ultrasound exam.

• Start at the stomach by locating it just caudally to the liver. Rock and fan the probe to systematically obtain orthogonal views of the whole stomach from fundus to pylorus.

• Next, examine the intestines and cecum. 

  • The duodenum, ileum, cecum, and colon are examined individually. 

  • For the jejunum, you don’t need to follow every loop from beginning to end. Instead, scan the abdomen starting at the level of the stomach. Slide or sweep the probe from side to side, gradually moving cranially to caudally until you’ve visualized the entire field (usually you would stop at the level of the urinary bladder trigone).

• Along the way, take notes to help you prepare your report for your patient’s medical record. Be sure to include what was normal, as well as any abnormalities you found, such as masses or thickened intestinal walls. 

While scanning, you can freeze images for your records and take measurements if you feel anything may be enlarged.

When you develop your ultrasound skills, having this tool at your disposal can often give you quick information when you need it—for example, looking for a GI mass or obstruction when x-rays were inconclusive.

It’s a great way to offer an additional service to your patients and clients, and possibly to stand out from other clinics in your region.

A Beginner’s Guide to Pathology Using Ultrasound

Sometimes, radiographs just don’t show the whole picture…

That’s especially true for analyzing the details of soft tissue structures—especially in the abdomen, but in other parts of the body as well.

Limitations of radiographs

One problem you may run into with radiographs is a “silhouette sign,” which basically means that two areas with a similar opacity border one another in your x-ray views. This makes it difficult to tell where one structure begins and the other ends.

A good example of a silhouette that could cause confusion is when the abdomen is full of fluid. Since fluid is approximately the same opacity as the abdominal organs, they may blend together, making it difficult to evaluate the abdominal structures.

In cases like this, an ultrasound can provide additional information. And, ultrasound has many other uses…

What an ultrasound is especially useful for

Radiographs can provide a lot of valuable information. But, they can’t always provide fine detail about texture, small defects, or other abnormalities of soft tissue structures. That’s especially true if the abnormalities don’t result in a big change in opacity or in organ size.

Therefore, ultrasound is often superior for detecting changes within an organ, especially if the change is small, in the early stages of a disease, or otherwise difficult to view on radiographs.

This may include conditions such as…

• Nodules or masses within an organ such as the liver, which aren’t large enough to change the radiographic silhouette/size of the organ.

• Pancreatitis or certain other disorders of the pancreas.

• Calculi of the urinary bladder that are radiolucent.

• Details of the gallbladder, an organ that is often difficult to see on radiographs since it is overshadowed by the liver.

• Abnormal blood vessels, such as a portosystemic shunt.

• Detailed cardiac evaluation, including diagnosing enlargements, congenital abnormalities, neoplasia, and more.

These are just a few examples—an ultrasound has many uses clinically!

Of course, there are some lesions that are better diagnosed using radiographs rather than ultrasound, especially in areas of the body that don’t transmit sound waves well (such as the lungs).

And, by looking at your x-ray views and ultrasound study together, you’ll get more information than you would with either technique by itself. 

So, it’s not a matter of choosing between radiographs and ultrasound—instead, they work very well when used together to see the whole clinical picture.

How to use an ultrasound

It takes some experience to get the hang of directing your ultrasound probe and interpreting the images. Taking a course is often the best and fastest way to become proficient.

However, even though the process of performing an ultrasound study is different from obtaining radiographic views, some of the basic principles of interpretation remain the same for both. 

Rely on the same good practices you do when reading a radiograph, such as…

• Have a system and evaluate each organ (and spaces between the organs) in an order that works for you. Do it the same way each time, to be sure you don’t miss anything.

• Examine cross-sectional images together—meaning views that are 90-degrees apart—of each area of study. An ultrasound, like an x-ray, produces a two-dimensional image. So, you’ll want to move the probe to look at each area at different angles (just like orthogonal views provide a complete picture when taking radiographs).

• When in doubt, seek a consultation with a radiologist who can help you interpret your images.

Just like any other part of your clinical skills, ultrasound technique and interpretation will come with time.

After all, they call it clinical “practice” for a reason—practice makes perfect. 

But with a little time, you’ll likely see a good ROI on your investment, since you can diagnose in-house rather than referring—and may find your ultrasound very useful if you need more diagnostic information in a pinch.

Diagnosing Tumors Of The Heart In Dogs And Cats

Cancers of the heart are uncommon in dogs and cats. When they do occur, it’s important to differentiate a tumor from other conditions that could cause generalized or focal enlargement of the heart and cardiovascular symptoms.

Which Cancers Occur In Cardiac Tissues?

A cancerous lesion based at the heart could be a primary tumor, or due to metastasis. 

Primary tumors that occur at the heart include:

• Hemangiosarcomas—the most common heart cancer in dogs, usually occurring at the right atrium. These occur most frequently in larger dogs with longer noses, such as Golder Retrievers, Doberman Pinschers, and German Shepherds.

• Chemodectomas, also known as aortic body tumors or heart base tumors. Generally thought to be slow-growing, these tumors occur most commonly in brachycephalic breeds like Boxers, Bulldogs, and Boston Terriers.

• Myxomas.

• Sarcomas.

• Ectopic thyroid tumors.

• Lymphoma/lymphosarcoma—the most common heart cancer in cats.

Other cancers are possible, but these are the most commonly diagnosed types. Breeds may vary as noted above, but most pets with tumors of the heart are middle-aged or older. 

How Are Heart Tumors Diagnosed?

If slow-growing, tumors near the heart base are often an incidental finding, seen on thoracic radiographs that are taken for another reason.

Other times, diagnostics are pursued because of clinical symptoms—which are often sudden in onset.

Once a mass is large enough to push on the heart and major blood vessels, many cardiovascular symptoms are possible, such as:

• Coughing

• Ascites

• Lethargy

• Weakness

• Vomiting

• Loss of appetite

• Difficulty breathing

• Collapse

• Sudden death

Note: If a dog presents with some of these symptoms, especially sudden weakness and collapse, a quick ultrasound scan may help to identify pericardial effusion and aid in guiding a needle for emergency pericardiocentesis.

Finding Heart Masses Early

As with most cancers and disease processes, discovering a problem earlier rather than later can allow for more treatment options.

General screening radiographs or ultrasound checks—such as with a senior wellness health check—can be a good opportunity to discover heart base tumors before they cause cardiovascular dysfunction and symptoms.

An echocardiogram performed via ultrasound can help to provide more information on the location, size, and invasiveness of the mass. 

In some cases, a presumptive diagnosis may be made based on the appearance and location of the mass on an ultrasound study, along with the patient’s signalment. If possible to perform without undue risk, an ultrasound-guided aspirate of the mass can provide more information about which type of tumor is present.

Treatment Options For Cancers Of The Heart

Treatment will be based on the type of neoplasia, how fast the mass is growing, whether metastasis is present, and whether or not the pet is symptomatic.

When a tumor of the heart is diagnosed, a good next step is to screen for metastasis and concurrent conditions via chest x-rays (if not already done), bloodwork, lymph node evaluation, and abdominal ultrasound.

Once a diagnosis is made, treatment options may include:

• Periodic monitoring with a cardiologist (especially for slow-growing chemodectomas/heart base tumors) prior to pursuing more invasive treatments.

• Surgery to remove the tumor.

• Pericardiectomy to remove the pericardium and prevent life-threatening cardiac tamponade or pericardial effusion. 

(A pericardiocentesis may be necessary on an emergency basis prior to diagnostics in a pet who presents with acute symptoms. After that, a planned pericardiectomy can help to prevent further emergency episodes of fluid buildup around the heart.)

• Chemotherapy, often in conjunction with surgery.

• Radiation therapy—either conventional, or via Cyberknife therapy.

Even though cancers of the heart are uncommon in pets, they can be scary to pet owners because of the possibility of sudden onset of serious clinical symptoms (especially with hemangiosarcomas).

By performing diagnostics, referring to specialists as needed, and giving your clients as much information as possible, you can help them make an informed decision for their pet.

Ultrasound Techniques: Visualizing the Adrenal Glands

The adrenal glands, those tiny but very important glands, can be tricky to find and evaluate during an ultrasound exam.

However, having a system and knowing where to look can make your job much easier.

There are many reasons you want to visualize the adrenal glands on every scan, including checking for neoplasia and other masses and looking for any changes that could be associated with Cushing’s or Addison’s disease.

Here are some tips to help save you time and allow for a clearer view of these small glands…

Have a repeatable system

When you perform an abdominal ultrasound, it’s important to have a systematic approach to look at everything. And that includes keeping small structures like the adrenal glands and abdominal lymph nodes on your list, so they don’t get overlooked.

Do your scan in the same order every time—whether that’s cranial to caudal, clockwise, or some other system that works for you—and it’s much less likely that anything will be missed or any abnormalities overlooked.

Adrenal gland landmarks

The right and left adrenal glands are respectively located near the right and left kidneys. However, the kidneys are relatively large, whereas the adrenal glands are small. So, the kidneys can overshadow these small glands.

The kidneys are the first things you’ll locate because they’ll point you in the right general direction. After that…

Vascular landmarks are most helpful when it comes to locating the adrenals.

Specifically, the aorta, caudal vena cava, renal vessels, and mesenteric artery are what you’re going to be looking for.

Color Doppler can help you visualize the vessels.

Also note, if the patient allows you to apply gradual pressure, it helps to minimize the distance between your probe and the glands as much as possible.

Finding the LEFT adrenal gland

The left adrenal gland is located ventrolateral to the aorta and cranial to the left renal artery. 

Start by scanning the left dorsal mid-abdomen and visualizing the aorta in a long view. 

Find the spot where the left renal artery branches off from the aorta, and just cranial to that you’ll see the left adrenal gland.

Finding the RIGHT adrenal gland

The right adrenal gland is dorsolateral to the caudal vena cava, and just cranial to the cranial mesenteric artery. It’s also more cranial and dorsal compared to the left adrenal gland.

Scan the right cranial abdomen, with the caudal vena cava in long view.

Apply some pressure with the transducer which will cause compression of the caudal vena cava and help you visualize the right adrenal gland. The gland is right next to the vessel, slightly oblique to it.

Are the adrenal glands normal?

Evaluate the qualitative properties of the gland, and then measure the glands from their cranial pole to caudal pole. Also, measure the thickness of each pole.

Normal adrenal glands are hypoechoic to surrounding fat, and have a characteristic “peanut” shape (although the right adrenal may have more of an “arrowhead” appearance). Typically, adrenals are 4-7mm thick in dogs and 3-4mm thick in cats. 

Abnormalities may include…

• Evidence of hyperadrenocorticism. 

  • If pituitary-dependent, the adrenal glands may be normal in appearance, or they may be “plump” (symmetrically enlarged). An ultrasound exam alone is not enough to diagnose Cushing’s, but may be helpful in context with additional diagnostic tests.

  • If adrenal-tumor related, you may be able to visualize a mass. 

• Evidence of Addison’s disease or hypoadrenocorticism.

  • You may notice smaller or thinner adrenal glands. As with Cushing’s, you’ll want to use this information in conjunction with clinical symptoms and other diagnostic tests.

• Adrenal masses.

  • Many are incidental findings only.

  • Pheochromocytoma is a possibility.

  • Malignancies are possible and may lead to invasion of adjacent tissues, especially blood vessels. 

  • You’ll use your clinical judgment and the patient’s clinical signs to help you determine whether more diagnostics are needed, or to start by monitoring the growth with repeat ultrasound exams over time.

• Age-related changes.

  • Nodular changes and remodeling may be normal in old adrenal glands. Practice will help to develop clinical judgment of what’s normal and what’s not.

The ability to find the adrenal glands quickly will come with experience, and knowing the right tips and techniques will make it easier to get the information you need even when you’re first learning.

10 Steps To Complete Dental Cleaning Procedures In Dogs & Cats

Ensure a pre-anesthetic checklist has been performed to include thorough patient history, physical examination, lab work, chest x-rays, and prophylactic medication use has been considered, particularly in the senior patient.

Ensure all equipment is functioning properly and that all essential instruments are available and sanitized. Ensure the CPR plan and CPR medications are in place, as well as resuscitation status for each patient. 

Provide a safe heat source such as a warm air blanket.

Continually check the patient by placing your hand directly on the patient under the heat source. Include this step on your anesthesia monitoring sheet.

Ensure the patient is warm during the pre-anesthetic phase where a patient’s body temperature can lower.

1. During the onset of anesthesia while intubating, use caution when handling the tongue, ensuring it is not pulled forcefully. Gently place the patient in position – note; placing a pet on their back during the entire procedure minimizes anesthesia time and is an effective and expeditious way to perform a dental.

Ensure the tracheal tube is adequately inflated, and an aspiration guard or gauze is in place. Consider the use of intraoral suction to prevent aspiration of water and debris during the procedure.

Continually replace gauze as it becomes saturated with water. Continually check the tracheal tube during the procedure as it may need adjusting depending on the depth of anesthesia and tracheal relaxation

2. While under anesthesia, take before and after photographs of all areas of the mouth to show the pet parent, as well as keep for documentation in the medical record.

3. Begin by irrigating the pet’s mouth with a dilute Veterinary Oral Health Council approved Chlorhexidine based rinse such as CET. Evaluate the oral cavity, and remove obvious calculus at this time to expose gingiva and soft tissues.

4. Perform intraoral regional nerve blocks prior to probing the teeth and gingival tissues, as this procedure may cause pain in the anesthetized patient, requiring a deeper plane of anesthesia. 

5. Thoroughly probe and chart each tooth, and perform full-mouth radiographs

6. Clean the teeth, perform extractions, and required orthodontic procedures needed. Ensure hand scalers and a curette are employed to remove subgingival calculus, particularly where periodontal pockets have been identified.

7. Thoroughly irrigate and lavage away oral debris.

8. Polish all surfaces of each tooth and subgingival areas thoroughly and carefully.

9. Rinse the mouth and each tooth with air and water and ensure all debris is removed from the tongue. Take post-procedure photographs.

10. Finally, apply a plaque prevention gel or dental sealant

Recover the patient quietly and employ pain management and anti-inflammatory medication. The post-anesthetic patient should be monitored closely post-surgically.

Post Dental Maintenance Of Dogs & Cats

Much attention is focused on the time leading up to and during dental work in dogs and cats, with much attention being placed on the dental procedure itself.

Without education of the pet parent, preventative care can fall to the wayside, leading to continued periodontal problems in the pet. 

Dental calculus can form hours after teeth cleaning, thus making the education of the pet parent a vital part of their pet’s dental health.

Properly educating the pet parent about post-dental preventative care entails a recheck visit a week or sooner after the dental, where the pet’s mouth is rechecked, handouts and dental preventative products are introduced to the pet parent, and a demonstration performed to demonstrate proper oral care techniques.

The best way of preventing gum and tooth disease in dogs & cats is to actively brush the pet’s teeth at least 3 to 4 times weekly.

There are some excellent products, including enzymatic toothpaste-like C.E.T. which can break down much of the tartar and debris on the teeth. 

During their recheck examination, pet parents can be shown how to brush their pet's teeth using a standard toothbrush, finger brush, and even gauze.

Emphasis should be placed on emphasizing the importance of making the effort to get the habit of home oral care started.

Other products that the pet parent can offer their dog or cat are chewable products such as C.E.T Hygiene chews, Greenies, and other over the counter dental products such as powders, sprays, and gels, as well as water additives.

During the post dental recheck visit, importance should be placed not only on the aforementioned but mentioning diet as well.

Pets eating canned food may be more susceptible to periodontal disease due to the sugars in the food, as well as the wet food sticking to the teeth.

Regular visits to the veterinarian for an oral health exam can give the pet owner an indication of how well they are maintaining the oral health of their pet.

Patient Injury & Complications In Veterinary Dentistry

The nature of anesthesia brings risk in general. In veterinary medicine, during dental procedures, pets are often placed in vulnerable positions which can lead to increased risk of injury and medical complications.

These risks can be minimized or entirely avoided with careful consideration, and proper training and continuing education of staff. Listed are a few of the more common injuries that can occur during a dental procedure.

Aspiration Pneumonia

Aspiration pneumonia in pet patients occurs when the patient inhales a foreign substance and develops lung inflammation and infection as a result.

The most common occurrence during dentistry is water and debris entering an unprotected airway, hence allowing fluid and debris to enter the lungs. This can occur from an underinflated tracheal tube, or repositioning during the procedure that allows fluid to enter the airway.

Aspiration pneumonia can also occur if the patient vomits or regurgitates during anesthetic recovery.. To reduce the incidence of dental-related aspiration pneumonia, maintaining the patient on their back during the procedure, and avoiding repositioning has proven to not only lessen the risk of aspiration but also lessens the amount of anesthesia needed during the procedure.

In addition, antiemetic medications given during the premedication phase can help reduce the incidence of post-anesthetic nausea and vomiting. Caution should be taken during the recovery phase to wait until the patient is alert and responsive enough to deflate the cuff and remove the tracheal tube.

Tracheal rupture

Tracheal rupture in dogs and cats are more frequent during dental procedures than any other medical procedure. Seventy-five percent of tracheal ruptures are thought to be associated with oral surgical procedures with the incidence more common in cats than dogs.

Tracheal injury can cause symptoms such as mild dyspnea, and even death. The most likely cause of tracheal rupture is thought to be due to an overinflated tracheal cuff, as well as failing to detach the tracheal tube from the anesthesia hose during repositioning, which can cause a torque on the inflated cuff resulting in a tear of the dorsal membrane of the trachea.

Another common cause of tracheal rupture is a patient that is not adequately anesthetized and coughs or lunges upward during intubation, tearing the trachea.

Pressure from an overinflated cuff can cause pressure necrosis of the trachea, showing delayed symptoms of inflammation and scarring.

Avoiding over-inflation of the cuff, using new tracheal tubes, testing the cuff to ensure proper inflation prior to use, avoiding repositioning as much as possible, and ensuring a level plane of anesthesia prior to intubation can help minimize the risk of tracheal rupture.

Artery Damage during Tooth Extractions

Arterial damage to arteries such as the palatine artery which runs the length of the mandible can accidentally occur during routine tooth extractions where the instrument can slip from the practitioner’s hand.

These injuries can be mild to more severe requiring surgical intervention.

The most effective way to avoid this type of injury is to implement extraction techniques involving gingival flaps where the roots are exposed, and more easily undermined, and extracted.

What Could You Miss Without Dental Radiographs?

When it comes to dentistry, sometimes teeth are like icebergs—there’s a lot going on “below the surface.” In this case, under the gumline. 

Unfortunately, the parts of the tooth you can see don’t always tell the whole story. 

That’s where dental radiography comes in.

Here are a few situations when dental x-rays could make your client communications easier, help you provide better patient care, and improve your bottom line…

Finding pesky root tips

If you’re extracting a tooth with a fractured root—whether the root splintered prior to the dental procedure or the tip happened to break off during a difficult extraction—you generally want to be sure you’ve removed each and every piece.

In many cases, root tips left behind can lead to infection, pain, or an abscess, plus another procedure to retrieve the piece and an unhappy client.

Radiographs help because you have confirmation that you’ve removed all pieces of the tooth roots.

For extractions, it can be useful to take “before and after” images that clearly document the successful removal of the tooth and its root(s).

Informing owners of the risk of jaw fractures

Sometimes, periodontal disease has caused so much bone loss that it leads to a pathological fracture in the jaw.

Or, the jaw could have so much bone loss that there’s a high risk of iatrogenic jaw fracture during a dental procedure and extraction.

You can probably imagine what could go wrong without radiographs…

When you extract the bad tooth, a jaw fracture can occur if that area of the mandible is already severely compromised due to disease and bone loss. But without radiographic proof of the underlying condition, the client may be inclined to blame your technique, rather than recognizing the severity of their pet’s periodontal disease.

Taking radiographs beforehand helps to set up realistic expectations of risk.

Discovering retained and impacted teeth

Whenever teeth are missing, dental x-rays are a good idea.

Sometimes, below the gumline, you’ll find retained or impacted teeth. Left in place, they could lead to dentigerous cysts or other problems.

Without radiographs, these “hidden” teeth can be difficult to find and treat.

Detecting damage to neighboring teeth

Maybe there’s one tooth that’s obviously bad… But, bone loss and infection have also affected the integrity of the neighboring teeth.

Dental radiographs will help you determine whether or not neighboring teeth are viable. And, the images provide tangible evidence that a neighboring tooth needs to be extracted.

This visual aid can make it easier to show a client exactly what you’re talking about, and help to reinforce your recommendations.

And more…

Dental radiographs can also help you look for oral neoplasias, feline resorptive lesions, tooth root abscesses, and more.

Sometimes this will help to confirm your clinical suspicions based on the patient’s presentation and symptoms. Other times, the findings may come as a surprise—allowing you to treat before the problem becomes worse.

With all the information dental x-rays provide, they can really help you create a thorough treatment plan that covers everything a patient needs during their dental procedure.

Your treatment recommendations can help to improve your dentistry revenue. And, importantly, your dental images can also help you provide excellent patient care and increase client knowledge and compliance.

Take The Frustration Out Of FORLs

To extract or not to extract that tooth root?

Is a crown amputation all that’s needed?

When it comes to feline odontoclastic resorptive lesions (FORLs), these may be the questions you’re asking yourself.

FORLs can cause loss of the protective surfaces (enamel, cementum, and dentin) of both the crown and the root(s) of a tooth, resulting in pain.

These lesions come in two varieties:

• Type 1: Where the root appears radiographically normal.

• Type 2: Where the root is radiographically hard to distinguish from the surrounding bone, with loss of visibility of the periodontal ligament space.

As you know, the treatment for these lesions is different—full extraction of the root(s) for Type 1, versus just a crown amputation for Type 2.

Performing a crown amputation and leaving a root in place for Type 1 could result in problems or complications, not to mention continued pain for the patient.

On the other hand, trying to extract the root of a true Type 2 lesion could be a monumental task and a big headache.

So, it’s very important to determine what type of lesion you’re dealing with. Here’s how…

Diagnosing FORLs

Patient presentation

A client brings their pet to you because of halitosis, food dropping, and occasional jaw chattering. 

During the physical exam, you notice bright red, inflamed gums and gingival hyperplasia near one of the mandibular premolars. 

You suspect a FORL—and given that FORLs are one of the most common dental problems in cats, you’re probably right.

You suggest a dental procedure, including dental radiographs, a full cleaning, oral exam, and possible extraction. The client agrees with the plan.

The day of the procedure

After the patient is anesthetized, your technician obtains radiographic images of the entire mouth, which takes just a few minutes to perform.

Then, you look at the radiographs in conjunction with your oral exam.

While probing the tooth in question, you feel a rough patch under the gingival hyperplasia, consistent with a resorptive lesion.

The x-ray confirms your diagnosis. 

Determining the best treatment plan

In this case, the patient’s tooth is clearly Type 1, with a periodontal ligament space still visible. So, you perform a full extraction.

While evaluating the dental rads, you also notice the premolar on the opposite side is starting to show radiographic evidence of a lesion.

Even though it’s mild, you call the owner and inform them of the likelihood of progression. 

To prevent a painful lesion from developing between dentals, the owner decides to go forward with a pre-emptive extraction of that tooth as well.

Documenting the extraction

In addition to being an integral part of your treatment plan decisions, dental radiographs can also help you document that extraction was performed successfully.

A post-procedure x-ray image is a great way to document that there are no root tips left behind.

And, in cases where a crown amputation was indicated, dental rads provide visual proof that this was an appropriate treatment course.

In this way, dental radiographs not only help you to plan and implement a very high quality of medicine—but they also give you peace of mind and are a valuable part of your medical records.

Talking to clients about dental radiographs

Maybe you already know the benefits of dental radiography—but you’re concerned about discussing the additional cost with clients. 

Often, it helps to include the x-rays as part of the dental procedure package. List them on the estimate so the client understands the value they are receiving—just don’t itemize the cost of the radiographs separately. 

Be sure to adjust the estimate of the dental package accordingly, to cover your costs. And remember, with a monthly payment plan for your dental radiography system, just a couple of dental procedures per month can cover your investment.

Client education also helps. Explain how the results of the radiographs allow you to provide the best possible treatment and reduce the likelihood of future complications.

With clients who want the best for their pets, it’s a win-win for both of you.

Ultrasound-Guided Cystocentesis: How and Why to Do One

There are several ways to collect a urine sample from your patient, including free catching, using a urinary catheter, and doing a cystocentesis.

A cystocentesis—which involves obtaining a urine sample via a needle placed directly into the bladder—may be the preferred method in many cases.

This is especially true when you need a sterile urine sample, such as for culture and sensitivity testing for UTIs. And in general, a cystocentesis will provide more accurate results than a free catch urine sample, since it reduces contamination from cells or pathogens of the skin.

It’s possible to perform a cystocentesis by palpating the bladder or using anatomical landmarks alone. However, an ultrasound can make the process easier by removing the guesswork and allowing you to visualize everything.

Here’s how it works…

How to perform an ultrasound-guided cystocentesis for dogs and cats

1. Prepare for the procedure.

   • Use an appropriate size syringe (usually 3ml to 12ml) based on the size of your patient.

   • Choose a needle size and length based on your patient size. A 22g needle works well for many patients.

   • Use a towel, trough, or other cushioning to make your patient more comfortable during the procedure. This may help minimize their movement.

2. Use appropriate patient restraint.

   • For some dogs and cats, this could mean having a trained team member hold them. For very anxious or fractious patients, this might mean chemical restraint.

   • Dorsal recumbency is generally the best way to position your patient.

   • Be sure to clean the area of skin where you’ll be performing the cystocentesis. If needed, consider clipping the fur, too. 

3. Estimate the bladder location.

   • You’ll use your ultrasound to see the bladder, but anatomical landmarks will give you a good starting point for where to place the probe. Try one of these methods…

     • Locate the caudal four mammary nipples and mentally draw an ‘X’ between them. The bladder will often be near the cross point of the ‘X’.

     • Place a small amount of alcohol on the caudal abdomen so it pools. Often, the bladder is located directly under where the alcohol naturally pools on the midline.

4. Visualize the bladder.

   • Place your probe onto the caudal abdomen. You should be able to see the urinary bladder on the screen—it’s a fluid-filled structure that has the appearance of a ‘black balloon’ with gray or white walls.

5. Check for any abnormalities.

   • You could focus on just doing the cystocentesis. However, while you’re visualizing the bladder, it may help to do a cursory exam (or even a more in-depth evaluation, if indicated) to look for any problems contributing to the patient’s urinary symptoms. 

     • For example, note if you see any thickenings, masses, calculi, or other issues in the urinary bladder.

6. Obtain the urine sample.

   • Place the needle directly through the abdominal wall, just in front of the ultrasound probe.

   • Aim the needle slightly caudally.

   • You should see the needle on your ultrasound screen. Use this visual to guide you, to be sure you get a good, clean sample rather than aspirating part of the bladder wall.

7. Prepare your sample for analysis.

   • Right after the cysto, replace the needle on the syringe with a sterile one.

   • Then, divide and prepare the sample in a timely manner (the fresher the sample, the better for testing) for any tests you need to perform, whether that’s in-house or at an outside lab.

In many veterinary hospitals, cystocentesis is safely performed several times per day, and complications are very rare. However, as with all medical procedures, some risks exist.

These may include…

• Hematuria (usually mild and transient).

• Much rarer complications such as bladder injury, leakage of urine into the abdomen, puncture of internal organs or blood vessels, or vagal reactions (retching, panting, hypersalivation, collapse). 

• Seeding of tumors.

  • If you suspect your patient has a bladder tumor such as transitional cell carcinoma, it may be best to avoid a cystocentesis. Otherwise, the needle could ‘seed’ the tumor as you withdraw your sample from the bladder, allowing cancer to spread into the abdominal cavity.

An ultrasound may help you to notice abnormalities such as bladder tumors during the procedure, in which case your recommendation to the client may change.

Fortunately for most pets, a cystocentesis is a quick outpatient procedure that provides a lot of valuable information. And many dogs and cats don’t show any side effects at all.

For patients with urinary symptoms, a cystocentesis is often the way to go for the most accurate diagnostic testing results and to get to the bottom of the issue faster for healthy pets and happy clients.

5 Tips for Radiation Safety During Uncertain Times

Your x-ray unit is something you use frequently—probably every day, or multiple times per day—in your practice.

You know radiation safety is important. But recently, if you’ve had to reduce the number of team members in the building at any given time, maybe it feels like there aren’t enough hands on deck for patient restraint and positioning.

The good news is, some of the same principles that reduce radiation exposure can also help your team operate more efficiently.

Here are some tips to maintain safety, even when you’re shorthanded…

A.L.A.R.A.: A Brief Reminder

A.L.A.R.A. stands for “As Low As Reasonably Achievable,” and it’s the guiding set of principles that help you reduce radiation exposure to yourself, your staff, and your patients.

This is important because ionizing radiation from x-rays can damage cells, and cumulative exposure can lead to health risks such as cancer and genetic damage to reproductive cells.

To minimize exposure, there are 3 principles to keep in mind:

• Time

• Distance

• Shielding

Decreasing exposure times, increasing the distance between your team and the x-ray source, and using PPE, all can help to decrease radiation exposure.

Tips for Radiography Safety and Efficiency

Hands-Free Restraint

Increasing the distance between your team members and the x-ray source is one of the most effective ways to decrease x-ray exposure.

Think of the inverse square law, which states that doubling your distance away from the x-ray source results in ¼ of the dose of x-ray radiation.

That’s a significant decrease!

Also, scatter radiation comes from the patient—so by not touching the patient, you’re reducing your exposure.

This can be accomplished by using:

• Chemical restraint.

• Positioning aids such as sandbags and tape.

• A combination of both.

In addition to contributing to safety, hands-free restraint also increases staffing efficiency.

Especially for large or wiggly patients, it takes fewer staff members to position the patient when hands-free restraint is used.

Patient Comfort

A patient who wiggles at the last moment can lead to a crooked radiographic image—and thus, the need to retake that view.

The more shots you take, the higher the x-ray exposure to your team members.

Keeping a dog or cat’s comfort in mind can help you get the shot you need the first time—and decrease the need for retakes.

Here’s how you can do this…

• Minimize fear and pain (for example, pain from stretching a sore leg to get the right position) by using chemical restraint. 

• Use a trough or other aid for comfort. Lying with their back on a cold, hard table can cause even the most cooperative of pets to squirm. Giving them a cozy place to settle into can really help.

• Play white noise or background music. This helps make the big buzzing and beeping sounds from the x-ray machine less startling to a dog or cat.

In addition to a better patient experience and less x-ray exposure, these methods help save your staff time by getting your views more quickly.

Getting Things Right the First Time

The fewer images you take, the less radiation exposure there will be.

In addition to the measures listed above, here are some ideas for taking the fewest views possible…

• Good planning. Be sure to know exactly which views you need ahead of time and what position the patient needs to be in for those views. Communicate these expectations clearly with your staff.

• Proper measurement. Measure the patient in the position they will be in during the shot (lying down rather than standing).

• Have a technique chart, or use appropriate settings in your digital unit. Teach team members how to make quick and accurate adjustments in settings, too.

• Use collimation. In addition to producing a higher-quality image, collimation decreases scatter radiation.

A thorough understanding of x-ray positioning and machine settings will save your staff time and headaches—in addition to minimizing radiation exposure.

Who Should Be in the X-Ray Suite?

Only the team members taking the radiographs should be near the machine. Clients shouldn’t be in the x-ray suite, and other team members should be fulfilling other duties—especially when you’re shorthanded.

Rotating the staff you have on x-ray duty can also help minimize their cumulative exposures. 

So, it’s smart to invest in training multiple team members. That way, you’ll also avoid delays if your “go-to” x-ray staff member ever needs to call out sick or otherwise miss a day.

PPE Care and Use

Even though the nature of your daily practice may have changed, it’s still important to keep up with x-ray safety measures, such as making sure your PPE is in good condition.

Experts recommend checking PPE every six months, and this includes radiographing your aprons, gloves, and thyroid shields to check for cracks. Of course, check and replace sooner if there are any notable defects.

Uncertain times may be stressful, but you and your team can continue to help the patients who need you while keeping yourselves safe.

Vomiting in Cats: Finding the Cause

Cats are good at hiding illness and pain. So, for some feline patients, it’s hard to tell what’s behind a bout of vomiting. 

A few of the many possible causes include:

• Hairballs.

• Food sensitivities.

• Dietary indiscretion.

• Infections or parasites.

• Stress.

• Pain.

• GI foreign bodies.

• Inflammatory conditions.

• Internal issues such as kidney disease or hyperthyroidism.

• Cancer.

Is it serious?

Often, it’s obvious whether the patient needs aggressive treatment right away or just needs a little bit of supportive care and observation at home.

However, other times it’s more difficult to know for sure. Those are the cases that may stay on your mind, making you wonder if the vomiting will continue or even become more severe.

It’s especially nerve-wracking if the patient went home for observation, but you’re concerned they may get worse overnight.

Reaching a diagnosis

Depending on the patient’s signalment, history, and physical exam findings, you’ll recommend the appropriate diagnostic tests.

Bloodwork

Bloodwork is a key factor in determining overall health status, and in establishing a baseline to monitor the patient for improvement or worsening of their condition.

These labs may be especially valuable in senior cats who have lost weight, when kidney disease, hyperthyroidism, or other internal medicine issues may be what comes to mind as the most likely diagnosis.

Imaging with x-rays and ultrasound

For some patients—especially if the vomiting is severe, or if you feel something abnormal on abdominal palpation—imaging may be needed right away. For patients with milder signs, you may decide to hold off on imaging at the first visit, but recommend the client bring their cat back if symptoms don’t improve.

And even if an obvious abnormality is noted on bloodwork (such as elevated thyroid hormone), imaging is still a good idea to rule out concurrent conditions, and to establish a baseline to compare any changes that show up on future imaging tests.

Either way, when it comes to imaging, radiographs are a good place to start. 

Radiographs give you a good overview of what’s going on inside the abdomen. You can look for masses, abnormal-looking organs, constipation, bladder issues, pyometra, signs of a GI obstruction, and much more.

However, sometimes more information is needed. Often, x-rays and ultrasound work well together to give you the full picture.

Ultrasound gives you additional clues about soft tissue structures, including:

• Differentiating a mass (size, what the borders look like, texture, thickness, etc.) from surrounding normal soft tissues. Silhouetting may make this interpretation challenging on x-ray images.

• Viewing bladder stones that aren’t radiopaque.

• Looking at small structures that are hard to see on x-rays, such as the adrenal glands.

• Inflammation of the GI tract or other internal organs.

• Finding evidence of a GI obstruction when it’s not obvious on radiographs (or, ruling out an obstruction—which may help you worry less if you decide to send the patient home for monitoring).

The list goes on, but the point is, x-rays and ultrasound can complement each other to give you the information you need, which can help you confidently diagnosis the mysterious vomiting cat.

Additional tests

Sometimes additional tests—for example, biopsies and infectious disease testing—may be needed to reach a diagnosis.

However, bloodwork, x-rays, and ultrasound are a great place to start. And often, these modalities will need to be completed prior to other modalities such as surgically obtained biopsies.

Lifestyle changes and monitoring

If the vomiting is due to a factor such as stress or hairballs, this may require a simple lifestyle change like providing Feliway diffusers and adding mental enrichment at home, or changing to a special diet.

But even in these cases, it’s good to rule out other, treatable medical causes—so a medical workup with diagnostic tests may still be recommended.

Keeping the vomiting at bay

If you have a patient with a chronic condition, you may recommend repeating the bloodwork, x-rays, and ultrasound at regular intervals.

A wellness checkup package that includes testing may be a good option for many patients—especially seniors. The wellness tests can be offered at checkups before the patient ever becomes ill, which gives you a great baseline for comparison with future test results.

Even though cats may not like to show symptoms of illness until a disease has progressed, wellness bloodwork and imaging (x-rays and ultrasound) can help to catch abnormalities early on, when the chances for treatment are better.

Bad Breath Can Mean Trouble

Bad breath, or halitosis, is one of those health problems that’s easy for pet parents to overlook.

Sure, it’s inconvenient. Stinky breath can certainly put a damper on a pet owner’s cuddle time or other interactions with their dog or cat.

However, many pet owners don’t realize that halitosis can mean something much worse… such as periodontal disease, or even an internal problem.

As a veterinarian, you know this very well—but it can be a challenge to communicate the dangers lying “under the surface” when it comes to bad breath.

Explaining halitosis to pet parents

The first step is figuring out where the bad breath is coming from, and explaining the potential risks to clients.

Dental problems such as periodontal disease are the most common cause of bad breath in pets. But sometimes, halitosis begins somewhere in the body other than the mouth.

Possible sources of halitosis include…

• Periodontal disease and other dental issues.

• A health condition such as kidney disease (an ammonia-like or unpleasant smell) or diabetic ketoacidosis (more of a sweet smell).

• Respiratory diseases.

• Digestive issues or dietary indiscretions.

• Objects (like branches or chicken bones) stuck somewhere in the mouth.

• Oral neoplasias.

• Certain toxins.

Based on your patient’s history and physical exam, you’ll determine the most likely cause of the bad breath, and decide if diagnostic testing is needed. 

If the patient in front of you seems otherwise healthy but has obvious terrible dental disease, you can probably assume the smell (or at least, a large portion of the smell) is coming directly from their mouth.

And if a dental procedure is indicated, you’ll likely do pre-op bloodwork, which will help to confirm the patient is otherwise healthy. 

A recap of periodontal disease

It all starts with plaque, that thin film that forms on teeth due to food and saliva. We get plaque as humans, too, but fortunately, plaque can be removed by tooth brushing.

If not brushed away, plaque hardens into calculus (tartar) within as little as 24-36 hours. Then, it accumulates more and more over time and harbors bacteria. Calculus can’t be removed by toothbrushing alone.

Soon, this calculus (and its resident bacteria) become very irritating to the gums—and they like to grow below the gum line, where it’s harder to observe the process visually. This results in gingivitis, an early stage of periodontal disease (a disease process affecting the structures that hold teeth in place) where the gums become red and inflamed and may bleed.

From here, as the periodontal disease worsens, it creates pockets in the gumline, destruction of the periodontal ligament, and even bone loss in the maxilla and mandible. In severe cases, this bone loss can cause jaw fractures.

This all leads to pain and tooth loss. And, opportunistic bacteria may enter the bloodstream via inflamed gums, traveling to and causing problems in organs such as the heart or kidneys.

Reminding clients of the dangers of periodontal disease can help them understand their pet’s bad breath is true health and quality of life problem—not just an inconvenience.

Evaluating and treating dental and periodontal disease

Your initial pre-op exam will be done while the patient is awake—ideally with the owner present so you can show them what you’re seeing.

However, awake exams don’t allow for a full oral assessment. And, dogs or cats who are painful might not let you get a good look.

So you’ll make a dental cleaning estimate based on your initial exam but explain to the client that the full assessment will be done during the procedure.

This assessment should include dental radiographs. Since much of the disease process starts below the gumline, x-rays are the only way to see the full extent of damage from periodontal disease.

Some patients will just need routine cleaning, while others may need significant dental extractions. And, you can talk to your clients about continuing dental care at home through tooth brushing and dental treats.

By providing this valuable service, you’ll be not only keeping your canine and feline patients in great health—but also increasing the human-animal bond by preventing halitosis from interfering with the quality time between a pet and their owner.
