Nuclear medicine imaging uses small amounts of radioactive material, a special camera, and a computer to create images of the inside of your body. It provides unique information that often cannot be obtained using other imaging procedures to help diagnose many types of cancers, heart disease, gastrointestinal, endocrine, neurological disorders, and other health conditions. Because nuclear medicine procedures are able to pinpoint molecular activity within the body, they may detect disease in its earliest stages when it is most easily treated.
