Assessment of colon motility using simultaneous manometric and functional cine-MRI analysis: preliminary results

摘要

Purpose Gastrointestinal functional disorders are common symptoms. The evaluation of underlying colonic motility dysfunction is difficult due to lacking adequate examination techniques. Recently cine-magnetic resonance imaging (MRI) was introduced as imaging technique for visualizing colon motility. However, the correlation of MR-visible colonic-movements and real intraluminal movements was not demonstrated yet. Therefore, this feasibility study’s purpose was to stimulate high amplitude propagated pressure waves (HAPPWs) by bisacodyl application under manometric control and to simultaneously identify them with cine-MRI.
