A PET scan, or Positron Emission Tomography scan, is an imaging technique that allows doctors to observe metabolic processes in the body. It involves injecting a small amount of radioactive material, called a tracer, which emits positrons as it decays. These positrons interact with electrons in the body, producing gamma rays that are detected by the scanner. PET scans are commonly used in oncology, cardiology, and neurology to detect diseases, assess treatment response, and evaluate brain function.
