Positron Emission Tomography (PET) for Miscellaneous Applications
Positron emission tomography (PET) images biochemical reactions and physiological functions by measuring concentrations of radioactive chemicals that are partially metabolized in the body region of interest. Radiopharmaceuticals or tracers used for PET are introduced into the body by intravenous injection or by respiration.The scanners used for PET imaging are very similar to those used for radiograph computed tomography, but PET requires more complicated technology and computerized mathematical models of physiologic functions and tracer kinetics for the generation of images.
Positron emission tomography (PET) is considered medically appropriate for imaging of brain as part of preoperative planning for epilepsy surgery.
