PET stands for Positron Emission Tomography. As the name suggests, these scans use the emission of positrons (a type of atomic particle) by a tracer drug to get a visual representation of the chemical processes and functions happening inside the body. The radioactive tracer is usually ingested, injected, or inhaled into the body. It emits a differential number of positrons based on blood flow, oxygen use and other metabolic activity markers at any given part of the body. These atomic emissions are then manipulated to provide a 3D image of the physiological processes occurring in the body. Any deviations from the normal that shows up on the scan indicates impaired functioning or disease.
