Nationwide Utilization of Virtual Colonoscopy Triples, Study Suggests
American College of Radiology (ACR)Medicare coverage and nationwide utilization of computed tomographic colonography (CTC), commonly referred to as virtual colonoscopy, has tripled in recent years, according to a study in the April issue of the Journal of the American College of Radiology (www.jacr.org). CTC employs virtual reality technology to produce a three-dimensional visualization that permits a thorough and minimally invasive evaluation of the entire colon and rectum. CT colonography is an alternative to conventional optical colonoscopy for colorectal cancer screening and diagnosis.
