Positron Emission Tomography (PET) is a medical imaging technique where radioactive 'tracer' isotopes which emit positrons are injected into a living subject. By measuring where the positrons 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 studies of the human brain.
