Computed Tomographic Colonography

Computed tomographic colonography (CTC) is a screening test that looks for signs of colorectal cancer. This test is also called a virtual colonoscopy.

A CT scanner takes X-ray pictures of your colon and rectum from outside your body. A computer arranges the pictures into a detailed image that can show polyps or other problems. Before the scan is done, the doctor inserts a thin tube into your rectum to fill your colon with air. Air in the colon makes polyps easier to see.

Sedation isn't required, and the test itself doesn't take much time. But a CTC requires the same bowel preparation as a colonoscopy.

If the doctor sees a problem during the test, such as a polyp or abnormal tissue, you will need to have a colonoscopy so a biopsy of the polyp or tissue can be done.

Due to the threat of the COVID-19 (Coronavirus), we are taking precautionary measures to protect our staff and patients. We are implementing a temporary NO VISITOR policy at this time. Only patients or patients and their guardians will be allowed into the office. Please note, this is not to inconvenience anyone! The virus is a very real threat and it is essential that we stay healthy in order to provide needed care for our patients. If you are sick, we ask that you CALL the office to speak with a nurse before you come in. The nurse will provide specific instructions for you. Please DO NOT enter the office if you are sick (upper respiratory symptoms, fever, cough, or flu like symptoms). We are closely monitoring the situation and will update you as circumstances change. Thank you for your understanding!!
