CT or CAT Scan (Computerized Axial Tomography) penetrates the body with a thin, fan-shaped x-ray beam and produces a cross-sectional view of body tissue. Conventional x-rays, which view the body from only one angle can be difficult to interpret when the shadows of bones, muscles, and organs are superimposed on one another. CT scanners allow the radiologist to view a "slice" of the body from many angles by moving the x-ray tube around the patient. A computer reconstructs the many views to make a single diagnostic image.
What to ExpectThe CT scanner consists of a large donut-like ring that your body passes through while laying on a movable, padded table. As the x-ray tube circles the body, the table moves in small measured increments, positioning you for the next image. These images are reconstructed by the computer to produce a diagnostic image of your internal anatomy. Occasionally, a contrast agent is administered either orally, or by injection into a vein to help make the image clearer. During the exam you will hear sound of motors running and the table moving. This is completely normal, just lie still and refrain from movement so that the images do not blur. The technologist will remain in constant contact with you both visually and via an intercom.
PreparationInstructions vary depending upon the body part to be scanned. Your physician or our technologists will give you specific instructions on how to prepare for your exam. If you are pregnant or nursing, let your physician or technologist know immediately.
How Long Will it Take ?Exams times vary depending on the body part being scanned. Our technologist can give you an estimate based upon the exam you are having.
