Computed tomography (CT) or CAT scans refers to a scanning process in which computer and x-rays are used together to create a cross-sectional picture of the body. A narrow x-ray beam circles around the specific part of the body that needs scanning and then produces series of images of that part from different angles. A trained radiology technologist performs CT scan under strict supervision. During the test procedure, the patient needs to lie down on the table inside the CT scan machine. The table moves under the scanner and records images. The test is painless, gives accurate results and takes very little time.
