FAQ - Virtual Colonoscopy

How is a Virtual Colonoscopy exam performed?
Virtual Colonoscopy is performed with a high-speed multidetector CT (Computed Tomography) scanner. The patient lies on a CT exam table and a small flexible enema tip will be placed in the rectum so that air can be introduced to expand the colon. A scan of the colon is performed with the patient lying on their back and then repeated while lying on their stomach. Each scan takes approximately 20 seconds with the total time for the procedure approximately 15-20 minutes.

How long does the exam take?
The actual examination portion takes approximately 20-30 minutes.

Who conducts the exam?
A Board Certified, Medical Doctor (MD) performs the rectal examination and inflation of the colon. A licensed Radiologic CT Technologist conducts the CT scan and assists the physician.

When and how do I get the results?
After the exam is performed, a Board Certified Radiologist will evaluate the images to detect colon polyps or cancers. A written report and CD of the study will be sent to you within 2 weeks.

What if the results show something abnormal?
In the event of abnormal findings, you are to call your personal physician as soon as possible to discuss your follow-up care. University MRI encourages all patients to share the written report and CD images with your personal physician regardless of the findings.

Will it hurt? Is it painful?
A patient can expect to feel some pressure as a result of the air being introduced into the colon. This minor discomfort can be compared to having gas.

When can I get an appointment?
Virtual Colonoscopy is scheduled Monday through Friday. Please call for appointment availability.
