Preferred Abstract (Original):

Aim of this study was to evaluate the practicability of real-time MRI regarding the assessment of gastric motility. Besides, the effect of motility-modifying agents were determined. Six healthy volunteers were examined using a real-time TrueFISP sequence before and after the intravenous application of scopolamine as well as metoclopramide. A motility index was calculated depending on antral peristalsis. Antral motility was quantified: administration of scopolamine led to a decrease, metoclopramide to an increase of gastric motility compared to the data lacking intravenous drug application.
