CT Colonoscopy

What is a Virtual Colonoscopy? 3-D image of colon - the green line is the pathway the computer takes through the colon looking for polyps and lesions.

A Virtual Colonoscopy (also called a CT Colonography) is a special type of x-ray that uses a CT scanner and computer software to examine the inside of your colon (also called your large bowel or large intestine).

Why should I have a Virtual Colonoscopy?

This procedure can detect ulcers, tumors (polyps), cancer or other illnesses. This test requires an order from your doctor, nurse practitionComputer generated image of inside the colon, normal, or physician assistant.

How long will the exam take?

The exam takes between 45 to 60 minutes to complete.
What do I do before the exam?

When your doctor orders the test, he/she will give you specific preparation instructions to follow. Make sure to ask about any prescription medications you might be taking. A thorough cleaning of your colon is necessary to get the best results. If you have any questions about the preparation instructions, please call our office at 743-0445.

What will the exam be like?

First, you will be asked to change into a gown and then escorted to an exam room. You will be placed on the exam table and a small, lubricated tube will be inserted into your rectum. This tube will fill your colon with air for the best possible x-ray picture.

The CT scanner consists of a narrow table and a large donut-shaped ring. For the exam, the table will move through the opening as a series of x-ray beams rotate around you. A computer in the machine will take these pictures and recreate a 3D image of inside your colon. You will need to remain still for the exam because movement can make the pictures blurry.

What happens with my test results?

One of our specially trained radiologists will study the x-ray films from your test and send a typed report to your doctor, nurse practitioner, or physician assistant. They can then discuss the results with you in detail.

What if I have further questions?

If you have any further questions or concerns about this procedure, please contact our office at 743-0445 or call your doctor, nurse practitioner, or physician assistant.
