PET Scan (Positron Emission Tomography)

A PET scan, or Positron Emission Tomography, is a medical imaging technique that helps doctors see how your body is functioning. It involves injecting a small amount of a radioactive substance, called a tracer, into the bloodstream. This tracer emits tiny particles called positrons as it breaks down. A special camera captures images of these emissions, allowing physicians to visualize metabolic activity in tissues and organs. PET scans are commonly used to detect cancer, assess heart conditions, and evaluate brain disorders, making them a valuable tool in diagnosing and monitoring various health issues.
