Inter- and intra-observer variability of software quantified bowel motility measurements of small bowel Crohn’s disease: findings from the MOTILITY trial

Motility MRI is a novel biomarker of small bowel Crohn's disease activity. Currently, limited data on intra- and inter-observer variability exists. Motility MRI shows moderate to good inter- and intra-observer agreement. Intraclass correlation was 0.59-0.71 for experienced and inexperienced radiologists. Motility MRI is reproducible, supporting its utility as a biomarker of disease activity.
