 CT
Computed tomography (CT), also referred to as computed axial tomography (CAT), is an x-ray technique that uses a special scanner and a computer to create cross-sectional images of the body. The CT Scan produces clearer, more detailed images of the part of the body being examined than can be accomplished by x-rays and is the preferred cross-sectional imaging test in most cases for examination of the chest, abdomen, pelvis, sinus, ear and some bones.
The patient lies on a table that slides into a large, circular opening in the doughnut shaped CT scanner. A succession of x-ray beams are passed through the body from many different directions. Detectors in the scanner receive these beams and send signals to a computer. The computer processes these signals and produces a cross-sectional image on a viewing monitor. The electronic digital images are then recorded for the radiologist to interpret.
Certain CT Scans are performed with a contrast agent. Also, for some CT scans, the patient may need intravenous injection of iodinated contrast to help make blood vessels, organs or abnormalities show up better on the scan.
A CT scan may range from 15 minutes to one hour, depending on the type of scan performed.
