Abstract
Computed Tomography (CT) gives 3-D morpho logical images of the object under test. Anatomica information from CT can be used to compensate the limits of radionuclide imaging techniques. First of al it can help in physically localizing the uptake site within the body of the animal, thus allowing the ana tomical identification of the site. The CT scan also helps in performing more accurate radionuclide quan tification studies.
