A new study from Mayo Clinic in Arizona shows that virtual colonoscopy isn't just for younger people. The study published in Radiology now indicates that virtual colonoscopy is comparable to standard colonoscopy for people older than 65 years old. A Mayo Clinic study published in the New England Journal of Medicine in 2008 indicated that virtual colonoscopy is as good as standard colonoscopy, but the performance in medicare age patients was not specifically analyzed. Questions lingered by some about the effectiveness of virtual colonoscopies in older people because of the increased occurrence of colon polyps. In the new study, data from the 2008 research study was used to evaluate the performance of CTC in patients over age 65 compared to those age 50-65. The study found no statistical significant difference in CTC effectiveness between the two patient groups. C. Daniel Johnson, M.D., Chair of the Department of Radiology at Mayo Clinic in Arizona, and coauthor of the study hopes this further validates virtual colonoscopy as a colorectal cancer screening option, and will encourage more people to be screened.
