    imaging technique that visualizes metabolic activity using radioactive tracers

    A Positron Emission Tomography (PET) scan is a medical imaging technique that helps visualize metabolic processes in the body. It involves injecting a small amount of radioactive tracer into the bloodstream, which accumulates in areas with high metabolic activity, such as cancer cells. The PET scanner detects the radiation emitted by the tracer, creating detailed images that can help diagnose and monitor conditions like cancer, heart disease, and brain disorders.
