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 cross section of anatomy and are attenuated or "filtered" as they travel through the body. Those which successfully make it all the way through the body are measured by special detectors which send the information to a computer. The computer then processes the information using mathematical calculations to produce a series of images. The images are displayed on a computer monitor for viewing and interpretation by the radiologist. These images are then saved electronically on a secure computer system (PACS) dedicated to the archiving and retrieval of medical images.
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. Refer to the Exam and Preparation Chart for proper instructions pertaining to your examination.
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 gantry, the circular opening of the scanner. For all scans, you must hold very still while the images are being acquired to ensure a clear picture. You may be instructed to hold your breath at different intervals during the scan. Some scans may require the administration of intravenous, oral, or rectal contrast to enhance vessels and to help visualize the intestinal tract. After completion of the scan, you will be asked to wait for a few minutes while the images are reviewed by the radiologist to ensure that no additional views are needed.
FINDING OUT THE RESULTS
Your CT scan will be examined by a board certified radiologist, a physician who specializes in medical diagnosis through imaging. The results of your examination will then be conveyed to the health care provider who ordered the examination who will then discuss the results of your examination with you.
SCHEDULING
Appointments should be scheduled ahead of time by your referring physician's office; however we will try to accommodate out-of-town patients and patients in need of urgent exams.
We have five locations in the area capable of performing CT exams: North Hills Office, West Raleigh Office, Cary Office, Garner Office, and Chapel Hill Office.
