Positron Emission Tomography (PET) is a powerful imaging technique that holds great promise in the diagnosis and treatment of many diseases, particularly cancer. A non-invasive test, PET scans accurately image the cellular function of the human body. In a single PET scan your physician can examine your entire body. PET scanning provides a more complete picture, making it easier for your doctor to diagnose problems, determine the extent of disease (staging), prescribe treatment, and track progress.
PET (Positron Emission Tomography) and CT (Computed Tomography) scans are both standard imaging exams that physicians use to pinpoint disease states in the body.
