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.
A positron emission tomography scan is an imaging test that uses nuclear medicine to view the body on a cellular level. The PET scan measures body functions, such as blood flow, metabolism and oxygen use, and may be used to detect disease, like cancer, and heart and brain problems.
