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.
PET stands for positron emission tomography. A PET scan produces three-dimensional, colour images of your body using radionuclides. See separate leaflet called Radionuclide (Isotope) Scan for more information on radionuclides. PET scans show where cells are particularly active.
