  "term": "Positron emission tomography",
  "field": "Chemistry",
  "definition": "A nuclear medicine imaging technique that uses radioactive tracers which emit positrons to produce three-dimensional images of functional processes within the body. When a positron annihilates with an electron, two gamma rays are produced in opposite directions, which are detected to localize the tracer. PET scans are widely used in oncology, neurology, and cardiology.",
