Authors' objectives:
This Technical Brief aimed to review evidence for the effectiveness and safety of computed tomographic (CT) colonography for the early identification and management of colorectal cancer.
Authors' recommendations:
The following findings and conclusions were made: 1. CT colonography is a relatively safe procedure compared to DCBE, and at least as safe as, or safer than, diagnostic colonoscopy. Ionizing radiation exposure is relatively low but a cumulative risk for regular screening. There is a very small risk of colonic perforation.
2. Generally there have been inconsistent findings regarding preferences for and experiences from CTC versus colonography. However one meta-analysis of 11 studies of increased risk or symptomatic patients concluded that CTC may be preferred over colonoscopy, and that the majority of studies have reported results favouring CTC over colonoscopy with respect to pain and discomfort.
