Khalaf A, et al. – Physicians designed this study to develop a methodology to evaluate pan–intestinal motility and transit in a single session using MRI and compare imaging findings to gastrointestinal (GI) peptide responses to a test meal and symptoms in a healthy volunteer cohort. In inducing a change in MRI motility end–points, the test meal challenge was effective, which would improve understanding of the pathophysiological postprandial GI response.
