A Positron Emission Tomography (PET) scan is a type of medical test that shows how parts of your body are working, not just what they look like. It uses a small amount of a special radioactive substance to highlight areas of activity, like how your brain, heart, or other organs are functioning. A PET scan helps doctors diagnose and monitor conditions like cancer, heart problems, or brain disorders. The scan is painless and provides detailed images that can guide treatment.
