PET Scan

A positron emission tomography (PET) scan shows how your tissues and organs are functioning. Radioactive tracers called radionuclides are used during the test to show the heart's activities. PET scans are useful to examine the chemical activity in various parts of your body to identify cancers, heart diseases, and brain disorders. Because PET scans measure chemical activity, they can help detect diseases before they are detected by other imaging tests. A cardiac PET scan can show areas of decreased blood flow in the heart to identify coronary artery disease and scarring.
