Emphasis is on the study of the functioning of organ systems: the endocrine system, respiratory and cardiac system, digestive system, gall bladder, skeleton system and central nervous system. Nuclear Medicine can be used to detect tumors or fractures. Frequently nuclear medicine provides results of dysfunction or disease before physical symptoms indicate the condition. Earlier detection provides a better outcome.
Nuclear Medicine combines use of radioisotopes and radiology to study all systems of the body. These studies are also used to evaluate sources of infection and to localize tumors.
The DAT SCAN study is used in diagnosis of Parkinson's disease.
