Diagnostic Nuclear Medicine
Nuclear Medicine uses radiopharmaceuticals, which is a combination of a radionuclide or radioactive iodine and some non-reactive material. Also called radiotracers, they emit gamma radiation, which is captured and utilized by a gamma camera to visualize organs. The gamma camera is not confining and most people do not feel claustrophobic. Nuclear Medicine studies the physiology of the organs, providing a non-invasive means to help diagnose certain diseases and various medical conditions.
Each radioactive tracer targets a specific organ or organ system. Depending on the type of scan you are having, the tracer may be administered orally or by intravenous injection. This may occur immediately or hours prior to the beginning of your scan. There are no reactions to the radiopharmaceuticals used in Nuclear Medicine. The amount of radioactive tracer you receive is small and your body will eliminate it within a few days.
