Radionuclide Organ Imaging
Radioactive isotopes ( also called radionuclides ) or a substance tagged with a radioactive compounds which emit gamma rays are ingested ( swallowed ) by or injected into a patient. A gamma camera detects the emitted radiation and produces an image of the emitted radiation. This technique is useful for determining the size, shape, location and function of body organs such as the brain, lungs, bones, and heart.
