What is Cone beam CT (CBCT)
Cone beam CT (CBCT) is a type of 3D imaging that uses X-rays, similar to regular CT scans. But instead of a fan-shaped beam, CBCT uses a cone-shaped beam, making it smaller, faster, and lower in radiation.
Why use Cone beam CT (CBCT)
Veterinary surgeons are finding CBCT especially useful for:
Maxillofacial disease: CBCT excels at imaging the complex structures of the jaws, teeth, and sinuses. This helps diagnose and treat dental problems, trauma, and tumors more accurately. Studies show it provides more detailed information than traditional X-rays.
Small and exotic animals: CBCT's compact size and lower radiation make it ideal for examining the heads and teeth of small pets and even exotic species like rabbits.
Joint disease: CBCT can reveal subtle changes in joints, helping diagnose fractures, dislocations, and arthritis, especially in areas with overlapping bones.
When not to use it?
CBCT isn't perfect for everything. Its uncollimated beam means it's not ideal for:
Soft tissue, thorax, or abdomen: These areas require more focused imaging, best achieved with regular CT scans.
Large animals: Scattered radiation makes images less clear in larger animals like big dogs.
The future of CBCT?
As vets see the benefits, CBCT is likely to become more common in veterinary clinics. Its ability to provide detailed 3D images can lead to better diagnoses, treatment plans, and ultimately, improved patient care for a wider range of animals.
Key points:
CBCT uses a cone-shaped beam for faster, lower radiation 3D imaging.
It excels at imaging the jaws, teeth, and joints in small animals.
Not ideal for soft tissue, thorax, or abdomen, or large animals.
Holds promise for improved diagnosis and treatment in veterinary medicine.
