Radionuclide scanning can detect tumors, blood clots, obstructions and other abnormalities.
Radionuclide scanning is unique in the fact that it can detect internal bruising or bleeding. In addition to this ability, radionuclide scanning is often used to examining bones, lungs, kidneys, the gastrointestinal tract, or the thyroid gland.
One type of nuclear scan, the MUGA scan, can show damaged areas of the heart and expose problems with the heart's pumping action. A small amount of radioactive material is injected into a vein, usually in the arm. A scanning camera records the nuclear material that is taken up by heart muscle (healthy areas) or not taken up (damaged areas).
