Positron emission tomography (PET) allows quantitative measurements of regional physiological and biochemical processes to be made in vivo in humans. PET determines the three-dimensional distribution of activity in the organ being studied after the subject is administered a tracer labeled with a positron emitting radionuclide. Quantitation of the parameter under study is accomplished by the use of a mathematical model that describes the biochemical or physiological process being examined.
