Nuclear medicine imaging is a subspecialty of diagnostic radiology that uses small amounts radioactive material to help to diagnosis and treat of disease. Nuclear Medicine is often used to evaluate how an organ or tissue is functioning, by assessing the metabolism and/or blood flow of the organ or tissue. The radioactive materials, called radiopharmaceuticals, give off energy in the form of gamma rays. Gamma cameras, positron emission tomography (PET) scanners, and/or probes are used to detect these energy levels, which produce special pictures for analysis. The small amount of radioactive material used is equivalent to a traditional X-ray, so it is within safe limits.
During a Nuclear Medicine test the small amount of radiopharmaceutical will be injected, swallowed or inhaled depending on which part of the body your physician desires to examine further. These tests are safe and painless. A gamma camera, PET scanner or probe, will then be used to evaluate the effects of the radiopharmaceutical in order to create images of the body. Nuclear medicine is unique to other forms of imaging because it is used to examine the biological changes within the body versus the anatomy changes.
