Tomography in which a computer-generated image of local metabolic and physiological functions in tissues is produced through the detection of gamma rays that are emitted when introduced radionuclides decay and release positrons.
PET/CT is used to help physicians more accurately diagnose and identify cancer, heart disease and brain disorders. PET/CT scans combine two scanning technologies—Positron Emission Tomography (PET) and Computed Tomography (CT)—into one procedure, producing a more accurate picture of what’s going on in the body than either scan alone. The PET scan produces images highlighting areas of high metabolic activity, and the CT scan produces pictures of the body’s internal structures. Put together, the combined image provides information about cell activity and its accurate location.
