Abstract
Purpose: The purpose of this study was to evaluate the effect of colonic distention in computed tomographic colonography (CTC). Methods: There were 3941 adults who underwent CTC with distention by either carbon dioxide (CO2; n=2099) or room air (RA; n=l733). Supine distention and prone distention were prospectively assessed and compared. Results: With CO2, distention on the supine view was superior in 72.1% (1514/2099) of the patients; with RA, the prone view was better in 56.8% (984/1733) (P<.0001). Conclusions: With CO2, the supine data set is more often the superior view, whereas with RA, the prone data set is more often preferred.
