Tomography used in diagnostic studies of internal bodily structures, in which computer analysis of a series of cross-sectional scans made along a single axis of a bodily structure or tissue is used to construct a 3D image of that structure. Also called computed tomography .
CT (computed tomography) uses highly sophisticated x-ray equipment and computer processing to obtain detailed images from different angles around the body. The introduction of CT scans in 1982 revolutionized non-invasive diagnostics by providing clear images of bone, organs, blood vessels and soft tissue. Today, technology has advanced to the point where multi-slice CT allows radiologists to view anatomy in a 3 dimensional fashion.
A CT scan is painless but it will require that you lie still for as long as five minutes. Some CT exams may require that drink a flavored oral contrast while others involve an intravenous (IV) contrast to be administered. CT studies are a useful diagnostic tool for many parts of the body including the head, neck, chest, spine, heart and numerous other areas.
