PET imaging (Positron Emission Tomography)

PET imaging (Positron Emission Tomography) is a medical scan that provides detailed pictures of how tissues and organs function. It works by injecting a small amount of a radioactive substance (tracer) into the body, which collects in areas of activity. The scanner detects the gamma rays emitted as the tracer decays, creating images that reveal metabolic processes. This technique is especially useful for detecting cancer, brain disorders, and heart conditions, offering insights into the body's functioning that go beyond static images, helping physicians diagnose and monitor treatments effectively.
