Nuclear scintigraphy, or scanning, is a form of diagnostic imaging that allows veterinarians to detect areas of increased bone metabolism that may signal orthopedic diseases, such as lameness. Bone scans can help identify problems in areas of the body that would otherwise be inaccessible. Scintigraphy also can be used as treatment for certain diseases. Dr. Kip Berry, a radiology specialist, returns to the show to discuss the therapeutic and diagnostic applications of nuclear medicine in small and large animals.
