Virtual
Colonoscopy
What is a Virtual Colonoscopy?
A virtual colonoscopy uses a computed tomography (CT or “CAT”) scan which is an advanced type of x-ray exam to acquire internal images of the colon.
This minimally invasive test provides a three-dimensional study of the large intestine that can ordinarily only be seen with the use of an endoscope inserted into the rectum. With this technology, polyps and lesions can be identifi ed. Because the entire abdomen and pelvis are imaged, abnormalities outside the colon are detected as well.
What should I expect?
Before the exam, you will be asked to change into an exam gown. The technologist will explain the procedure, provide instructions and answer any questions you may have.
During the study, you will be asked to lie on the CT table and a very small tube will be inserted into your rectum to allow air to be gently passed into the colon so possible polyps or masses can be easily identified. Most patients who have virtual colonoscopies describe a feeling of fullness during the exam, as though they need to pass gas. However, few experience significant pain.
There will be two sets of images taken, the fi rst on your back, the second on your stomach. As the table moves through the donut-shaped scanner, you will be asked to hold your breath for about 15 seconds.
The entire exam takes
about 20 minutes.
Once it is completed, the tube is removedand you will be free to leave and return to your normal activities.
How should I prepare?
It is very important to have your colon adequately cleaned prior to this exam. A prep kit and instructions will be provided 72 hours before your appointment.
There is a special diet that should be followed for 3 days prior to the exam. Within the prep kit are laxatives, a mild barium preparation and directions for their use. You should continue your prescription medications unless told otherwise. Diabetics may need to delay taking their medication on the morning of the exam until after they have eaten. Women should inform their technologist if there is a possibility that they are pregnant.
How do I get the results?
After your study is over, the images will be evaluated by one of our board-certifi ed radiologists with expertise in Virtual Colonoscopy. A fi nal report will be sent to your doctor, who can then discuss the results with you in detail. Should you have any questions regarding the Virtual Colonoscopy exam, we will be happy to discuss them with you.
Virtual Colonoscopy is covered by most insurances and is considered a preventative screening procedure.
A doctor’s order is required.
