CT ScanWhat Is a CT Scan?CT Scan sometimes called CAT scanning is a painless and a non-invasive medical test that helps physicians diagnose and treat medical conditions. CT uses a very thin special X-ray beam to produce detailed, cross sectional views of the area being studied. The images can be examined on a computer or printed. CT is often the preferred method of diagnosing causes of pain and many different forms of cancer. CT of the internal organs, bone, blood vessels and soft tissue provide greater clarity than conventional x-ray exams. Common Uses of the procedure:
How Is the Procedure Performed?You will be lying flat on a table usually on your back, stomach or on your side. The table will move slowly through the machine as the actual CT scanning is performed. You may be asked to hold your breath during the exam. The CT exam is usually completed within 30 minutes. How To Prepare For a CT?You should wear loose-fitting comfortable clothing to your exam. You may be given a gown during the procedure. You may also be asked to remove any jewelry, eyeglasses, dentures and hairpins which effect the CT images. Do not drink or eat anything for several hours beforehand, especially if contrast material will be used in your exam. Inform your physician if you are taking medications and if you have any allergies. What Does the Equipment Look Like?The CT scanner is a large machine with a hole (tunnel) in the center. A movable exam table slides into and out of the tunnel. The X-ray tube is in the center of the machine which rotates around you. The computer that processes the image information and monitor are located behind windows in a separate room.
