CT colonography is a minimally-invasive exam used to produce images that screen for cancer or polyps in the large intestine. Unlike traditional colonoscopy, the imaging is done from the outside by the CT scanner, not by a scope that is inserted into the rectum.
Colon cancer is one of the most common forms of cancer in adults. Early detection of colon cancer may help improve outcomes and increase your chances of survival. Be aware that, unlike colonoscopy, polyps or other abnormalities cannot be removed during a colonography. If polyps are found, you will have to schedule a colonoscopy to have them removed.
Please refer to the About CT section for more details about CT scanning and the associated risks and benefits.
Since early detection improves outcomes, professional organizations, such as the American Cancer Society, recommend colon cancer screening in adults starting at age 45. CT colonography is one of the tests suggested to be used for screening once every five years. The goal of screening is to detect pre-cancer or cancer at the earliest stage possible before symptoms appear. Individuals who are a higher than normal risk for colon cancer may start screenings at a younger age.
CT colonography may be recommended for you if you are reluctant to have a standard colonoscopy, if colonoscopy poses a risk for bleeding or other issues, if sedation is risky, or if you have bowel tumors or other obstructions.
To schedule a CT colonography, please call our scheduling team at (512) 453-6100 or toll free at (800) 998-8214. A provider referral is required to make an appointment.
A radiologist, a physician specifically trained to interpret radiological examinations, will analyze the images and send a signed report to the provider who referred you to ARA. The physician will then share the results with you. Your report will also be available on the patient portal within 3 business days your exam.
