Alberta Veterinary Dentistry Now Offers Cone Beam Computed Tomography


Cone Beam Computed Tomography – or a “CBCT” is a form of diagnostic imaging that scans bone and/or soft tissue. Once the image is fully rendered, the anatomy scanned can be explored in cross-sections for any abnormalities.


Cone Beam CT vs. Radiography

The main difference between general radiographs and the CBCT is that conventional x-rays only show a 2D image. With a 2D image, anatomical structures can overlap with one another, obscuring important pathology. With 3D imaging, this is completely avoided. Anatomy can also be viewed in cross-sectional views, making sure nothing significant is missed, especially when it comes to the head. CBCT can observe pathology with much greater accuracy and in less time than conventional x-rays.

Other Considerations for CBCT


If there is worry about blood supply access to any surgical areas (i.e. tumor sites), then intravenous contrast medium can be injected while the patient is under sedation or general anesthesia for the scan. This makes the blood vessels become bright on the image and lets the radiologist and surgeon create a better surgical plan. Direct measurements can also be added onto the cone beam scan, so the surgeon knows where any lesions are located down to millimeters!
