Computed Tomography

 Computed tomography (CT) is an imaging procedure that uses special x-ray equipment to make detailed pictures, or scans, of areas inside the body. It is sometimes called computerized tomography or computerized axial tomography (CAT).     Each picture created during a CT procedure shows the organs, bones, and other tissues during a thin “slice” of the body. The entire series of images produced in CT is sort of a loaf of sliced bread—you can check out each slice individually (2-dimensional pictures), otherwise you can check out the whole loaf (a 3-dimensional picture). Computer programs are wont to create both sorts of pictures.   Present day CT machines take consistent pictures during a helical (or winding) design as opposed to taking a progression of pictures of individual cuts of the body, on the grounds that the first CT machines did. Helical CT (additionally called winding CT) has a few points of interest over more established CT methods: it's quicker, delivers better quality 3-D pictures of regions inside the body, and ought to distinguish little variations from the norm better.    CT is widely wont to help diagnose circulatory (blood) system diseases and conditions, like arteria coronaria disease (atherosclerosis), vessel aneurysms, and blood clots; spinal conditions; kidney and bladder stones; abscesses; inflammatory diseases, such as ulcerative colitis and sinusitis; and injuries to the head, skeletal system, and internal organs. CT imaging is also used to detect abnormal brain function or deposits in adult patients with cognitive impairment who are being evaluated for Alzheimer’s disease and other causes of cognitive decline.
