Abstract

Purpose: To evaluate patient acceptance of computed tomography (CT) colonography compared with conventional colonoscopy by means of a self‐assessed questionnaire. Material and Methods: Four‐hundred‐and‐one patients with valid address information from our patient collective were preselected. Patient acceptance was evaluated retrospectively using a self‐assessed questionnaire. The patients underwent CT colonography in our institution using 4× or 16× multi‐detector row (MDR) CT. Two‐hundred‐and‐forty‐six patients returned a completed questionnaire, 157 of these indicating that they had undergone both virtual and conventional colonoscopy. Results: One‐hundred‐and‐twenty (76.4%) of the 157 patients would undergo another CT colonography if necessary, while only 14 patients would not. One‐hundred‐and‐sixteen (73.9%) patients favored the actual examination procedure of CT colonography ( P <0.0001), while only 6.4% preferred the conventional method. Preparation prior to CT colonography was experienced as more convenient than preparation prior to conventional colonoscopy (52.2% versus 14%). Conclusion: CT colonography was preferred in terms of both preparation and the actual procedure itself.
