Dynamic (cine) MRI of bowel motility is now routinely performed in clinical practice and advances in post-processing have enabled robust quantitation of this data facilitating numerous research applications. Generally, motility sequences are acquired in a 20 second breath hold at a temporal resolution of 1 fps. In this study, we investigate these core assumptions and provide guidance information for future studies. In summary, we show that a temporal resolution of at least 1 fps is necessary for a scan duration of at least 10 seconds. This is consistent with the majority of small bowel motility studies to date.
