PET is a powerful diagnostic test that is having a major impact on the diagnosis and treatment of disease. Because disease is a biological process and PET is a biological imaging examination, PET can detect and stage most cancers, often before they are evident through other tests. A CT scan also called Computed Tomography is carried out by using a special X-ray machine, which produces an image of a cross section, or slice of the body. Most common medical tests, like CT and MR scans, only show details about the structure of your body. PET is different. It also provides information about function. Therefore a combined PET-CT scan can provide both functional and structural information of the entire body in the study, thereby uncovering abnormalities that might otherwise go undetected.
