A Positron Emission Tomography, or PET, scan is an imaging technique that uses positively charged particles (radioactive positrons) to detect subtle changes in the body's metabolism and chemical activities. A PET scan provides a color-coded image of the body's function, rather than its structure. A PET scan may be used to evaluate patients with cancer, brain diseases, and cardiac illnesses.
