Positron Emission Tomography (PET)/Computed Tomography (CT) is a new non-invasive diagnostic imaging procedure that produces images of small changes in cellular metabolism in combination with detailed anatomical images. A very small amount of radioactive “tracer” (radionuclide or radioisotope) is injected into a vein by a PET/CT technologist. The radioactive “tracer” is tagged to a form of sugar that is used for energy by all cells in the body. Areas of abnormally high uptake of the “tracer” appear as brighter areas on the scan.
