| CT (COMPUTED TOMOGRAPHY)
A special type of x-ray that produces images of the body in cross sectional anatomy.
HOW DOES CT WORK?
In CT, x-rays pass through the desired part of the body and they are changed as they travel through the body. The x-rays are measured by special detectors that send the information to a computer. The computer then processes the information to produce an image. The image is displayed on a monitor for viewing and then transferred to x-ray film for a permanent record.
GETTING READY
Depending on the part of your body being examined, there may or may not be preparation involved. Your doctor will provide specific instructions to fit your particular situation. Be sure to follow your doctor's instructions carefully.
WHAT SHOULD YOU EXPECT DURING YOUR CT SCAN?
A CT scan is performed with you lying on a padded table. The table moves you into the circular opening of the scanner, which is just one foot deep. For all scans, you must hold very still while the images are being made to ensure a clear picture. You may be instructed to hold your breath at different intervals during the scan. Some scans may require administration of intravenous or oral contrast to enhance vessels and to help visualize the intestinal tract. After the scan, you will be asked to wait for a few minutes while the images are reviewed.
FINDING OUT THE RESULTS
Your CT scan will be examined by the radiologist, a physician who specializes in medical diagnosis by x-ray. The radiologist reports the results to your physician's office.
