A positron emission tomography (PET) scan is an imaging test that allows your doctor to check for diseases in your body. The scan uses a special dye that has radioactive tracers. These tracers are injected into a vein in your arm. Your organs and tissues then absorb the tracer.
A PET scan shows if your heart is getting enough blood or if blood flow is reduced because of narrowed arteries. It also shows dead cells (scars) from a prior heart attack. A PET scan can help in determining if youâll benefit from a cardiac procedure (PCI) or surgery to restore blood flow. The tracers used for PET scans can help identify injured but still living (viable) heart muscle that might be saved if blood flow is restored.
