Abstract
Computed tomography colonography (CTC) is established as the best alternative to optical colonoscopy (OC) for detecting polyps and tumoral lesions in the colon. In that way, it is an accepted modality after incomplete OC in patients with a contraindication for or who are unwilling to undergo OC [1]. Furthermore, CTC can be suggested for individual colorectal cancer screening and for patients with symptoms suggestive of colorectal cancer in general [2]. Adequate training and experience are considered crucial for accurate polyp detection [3]. However, besides being a champion in polyp detection, it is also very important for the radiologist to be familiar with findings of benign colonic disease and findings mimicking disease (polyps and tumors), as this will significantly reduce false-positive findings and hence superfluous OC. This issue of false-positive findings at CTC should absolutely be reduced to a minimum to avoid patient anxiety and because of increased costs.
