Nuclear Imaging

A nuclear medicine scan uses radioactive isotopes to create an image of an organ or internal area of the body in the diagnosis of disease. The images are recorded using a Gamma camera or sometimes with positron emission tomography (PET) or single photon emission tomography (SPECT). To create the image, a small quantity of radioactive material is injected intravenously to the patient. Once the radioactive material is injected into the patient there is a slight time delay prior to the start of the gamma camera. The gamma camera moves along the body of the patient taking numerous images of the inside anatomy.
