MR colonography group favors dark-lumen technique, air- versus water-based distension
By Eric Barnes
The German researchers who pioneered MR colonography (MRC) have been expanding their evaluation of the dark-lumen imaging technique they conceived in 2001. In two newly published articles, the radiologists from University Hospital in Essen discussed the efficacy of dark-lumen imaging, and investigated the effect on the technique of air versus water as a contrast agent.
