For most nuclear imaging studies, radionuclide is injected into the patient and the images are taken with a gamma camera suspended above the patient who will be lying on a table. The camera detects the gamma rays emitted from the radionuclide in the patient's body and uses this information to produce an image that shows the distribution of the radionuclide within the body. The image is recorded on film and is called a radionuclide scan.
