Computerized Tomography (CT Scan)

A CAT (Computer Assisted Tomography) Scan is also known as a CT (computerized tomography) scan.  Our CT scanners perform spiral scans -- the newest and fastest scanning technology available.  A CT scan provides cross-sectional x-rays of the body which are called slices.

CT scans were originally developed for diagnosing disorders of the brain, but are now used to image tissues throughout the entire body.  Because of the clarity and detail provided by a CT scan, patients can potentially avoid exploratory surgery.  Because a CT scan uses an ultra-thin, low dose X-ray beam, radiation exposure is minimized.  CT scans also provide greater detail than a regular x-ray and can provide a more detailed visualization of the internal organs and soft tissues.

About the Procedure

Depending upon the area of the body being imaged, you may be asked to drink a flavored mixture, called contrast, that will aid in the evaluation of your stomach and intestines.  When you enter the examination room, you will be asked to lie on the CT table and for certain types of examinations, intravenous contrast material may be needed.  The table will be moved so that the correct part of your body is examined.  You will be able to see out both ends of the scanner.  The technologist will be able to see you at all time and will communicate with you via a two-way microphone.  The exam usually takes from 10 to 30 minutes - allowing for preparation as well as time for the computer to generate the images.  Actual x-ray exposure time is minimal.  Your images are then evaluated by one of our physicians who has expertise in CT imaging.
