A positron emission tomography (PET) scan is a type of nuclear imaging test that shows the metabolic activities (energy usage) of your brain. While X-ray, CT, and MRI scans look at the anatomy of your brain, a PET scan can give your doctor information about how your brain is working.
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.
