In recent years the radiology community has embraced the potential offered by the fast developing world of CT colonography (CTC), since it offers an accurate, rapid and minimally invasive means of imaging the large bowel. The CTC option is also embraced by patients. In a survey of over 2,000 patients who had received both CTC and optical colonoscopy, 46% expressed a preference for CTC vs 24.9% who preferred optical colonoscopy¹. In addition CTC has been shown to be cost effective and to improve colorectal cancer prevention rates².
