Positron Emission Tomography (PET) is a nuclear medicine medical imaging technique where radioactive 'tracer' isotopes which emit a positron are injected into a living subject (usually blood circuit). After traveling less than one millimeter the positron annihilates with an electron, producing a pair of gamma ray photons in opposite directions. The technique depends on simultaneous or "coincidental" detection of this pair of photons: photons which do not come in pairs (within a few nanoseconds) are ignored. By measuring where the gamma rays end up, their origin in the body can be plotted, allowing the chemical uptake or activity of certain part of the body to be determined. It is used heavily in clinical oncology (medical imaging of tumors and search for metastases) and in human brain and heart research.
Radionuclides used in PET scanning are typically isotopes with short half lives such as Carbon-11, Nitrogen-13, Oxygen-15, and Fluorine-18. Due to their short half-lives, the isotopes must be produced in a cyclotron at or near the site of the PET scanner. These isotopes are incorporated into compounds normally used by the body such as glucose, water or ammonia and then injected into the body to trace where they become distributed.
