PET

PET, or Positron Emission Tomography, is a medical imaging technique that shows how tissues and organs function. It involves injecting a harmless radioactive substance called a tracer, which collects in specific areas of the body. The PET scanner detects the radiation emitted by the tracer and creates detailed images that reveal metabolic activity and blood flow. This helps doctors identify abnormalities like cancer, brain disorders, or heart problems early on, often before structural changes occur. PET is a powerful tool for diagnosing and monitoring various health conditions by providing insights into the body's physiological processes.
