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 PET scan (positron emission tomography) is an imaging test that can help reveal how your tissues and organs are functioning. To show this chemical activity, a small amount of radioactive material must enter your body.ET scan is often combined with other imaging tests, such as CT scan and MRI. The combination of the tests improves the clarity of the images and makes it easier for the physician to interpret the results.
