title: Gastric motility: comparison of assessment with real-time MR imaging or barostat measurement initial experience.
abstract: Measurements of gastric volume and motility with magnetic resonance (MR) imaging were compared with simultaneously performed measurements with a barostat in six healthy volunteers. Three-dimensional volume and two-dimensional dynamic MR images and barostat measurements were obtained at rest. Alterations in gastric volume and motility were induced by means of infusion of glucagon and erythromycin, respectively. There is strong evidence to have the opinion that MR imaging is as accurate as barostat measurement in determining changes in gastric volume, and it yields additional information about gastric contractions.
