Positron emission tomography (PET) and computed tomography (CT) are standard imaging tools that physicians use to pinpoint disease states in the body. The PET scan demonstrates the biological function of the body before anatomical changes take place, while the CT scan provides information about the body's anatomy such as size, shape and location. By combining these two technologies, physicians can more accurately diagnose and identify cancer, heart disease and brain disorders. PET/CT is a noninvasive procedure.
