Description: PET is a nuclear medicine medical imaging technique that produces a 3-D image of functional processes in the body. A PET scan uses a small amount of a radioactive drug, or tracer, to show differences between healthy tissue and diseased tissue. The most commonly used tracer is called FDG (fluorodeoxyglucose), so the test is sometimes called an FDG-PET scan. Before the PET scan, a small amount of FDG is injected into the patient.
Developed in 1975, the PET scan is a diagnostic tool that allows doctors to picture of how the cells in your body are working and to detect abnormalities. You may not have heard as much about PET scans as you have about MRIs and CT scans.
