Sali L, et al. - In a randomised trial, researchers evaluated the bowel preparation experience of patients and screening procedure for reduced cathartic preparation CT colonography (r-CTC) and full cathartic preparation (f-CTC) that showed similar detection rate for advanced neoplasia. Investigators found that for screening CT colonography, reduced bowel preparation is better tolerated than full preparation. Bowel preparation is not influenced by procedural discomfort of screening CT colonography. They observed that males tolerate better than females bowel preparation and CT colonography screening procedure.
