PET for pets

Positron emission tomography (PET) is an emerging imaging technology. It is becoming the standard of care for function imaging of tumors. To improve anatomic detail, PET studies are fused with computed tomographic studies (CT). Most PET studies use 18F-FDG as a glucose analog. Any lesion with increased glucose metabolism will have increased uptake of 18F-FDG. This helps distinguish between sites of active and normal glucose metabolism. Increased glucose metabolism occurs before enlargement of organs, allowing earlier detection of lesions. If an animal is imaged before and after therapy, then PET/CT provides information about response to treatment. The goal of this study is to evaluate the usefulness of PET/CT in dogs that have a variety of diseases, including cancer.
