Seacoast Radiology is now offering CT Virtual Colonography
Seacoast Radiology is now offering CT Virtual Colonography (VC) at Wentworth-Douglass Hospital and will be offering it soon at Frisbie Memorial Hospital. Our radiologists who interpret CT Colonography have received additional specialized training through the American College of Radiology (ACR).
VC Is a Safe Alternative
Virtual colonography is a safe alternative to conventional endoscopic colonoscopy. In fact, it is slightly safer than conventional colonoscopy since no intravenous sedation is required; IV sedation is always used with conventional colonoscopy and carries a very low but definable risk of respiratory failure. Additionally, many patients also experience grogginess and nausea following IV sedation. These are avoided with Virtual CT colonography. The same colon prep is, however, still required for virtual colonography.
What Happens if a Suspicious Lesion is Found
Patients should be aware that if a suspicious lesion is found on virtual colonography, you will typically need to undergo conventional colonoscopy for further evaluation and possible biopsy. If, however, your study is normal, you are done until the next scheduled screening exam! VC for both screening and for failed colonoscopy is covered by many insurers. Please talk to your physician if you are interested in screening colonography.
