Virtual Colonoscopy


Colonoscopies are a vital tool for finding and removing intestinal polyps. While most polyps are benign, some can grow and turn into cancer. Finding them early is key.

For this reason, most physicians recommend that everyone 50 and older should have a colonoscopy every seven to 10 years to screen for polyps. If you are at increased risk, it’s recommended you be screened every five years. Risk factors include a history of polyps, a family history of colon cancer, and/or the presence of blood in your stool.

Compared to a traditional colonoscopy, virtual colonoscopies take less time and don’t require a doctor to insert a scope into the entire length of your colon. Virtual colonoscopies also don’t require anesthesia, so you can quickly return to normal activities after your test.

Advanced Imaging Of Montana

CT, or virtual, colonography uses X-rays to take cross-sectional images of your abdominal cavity and colon. These images are assembled by a computer into a 3D rendering allowing the radiologist to “fly-through,” or virtually examine your colon and large intestine for polyps and other lesions. We use the latest in high-speed, digital CT equipment — resulting in shorter scan times and proper radiation doses.

About Your Visit

During the scan, a small enema tip is inserted into your rectum and air is used to inflate the colon. Once you are on the CT scanner, our technologist will direct you into the proper positions to get the necessary images. You can resume normal activities after the scan, but you may experience some bloating or pass gas for a few hours after the procedure.

Prep & Safety

Prior to your virtual colonoscopy your physician will give you a prescription for a bowel prep. Begin the prep, as outlined in the prescription, the day prior to your exam.
