BACKGROUND Recently,a technique has been developed to use magnetic resonance enterography(MRE)for the evaluation of small bowel *** hypothesis was that assessment of the motility index(MI)should reflect differences in motility between clinical *** To aim of the present observational,cross-sectional study was to evaluate the use of the MI in daily clinical *** All consecutive patients aged 18-70 years who were referred for MRE at the Department of Radiology during a 2-year period were asked to *** volunteers were included as *** was prepared and conducted in accordance with clinical *** the day of examination,all the participants had to complete the visual analog scale for irritable bowel syndrome(IBS)and IBS-symptom severity *** of MI were calculated from dynamic MR *** was used to evaluate differences in MI between groups,classified as healthy,Crohn’s disease,ulcerative colitis,IBS,other assorted disorders and *** and linear regression were applied to the MI *** medical records were scrutinized for medical *** In all,224 examinations were included(inclusion prevalence 76.3%),with 22 controls and 202 *** was a significant difference in the MI of the jejunum(P=0.021)and terminal ileum(P=0.007)between the different *** MI was inversely associated with the mural thickness of the terminal ileum in men(Pmotility on MRI was accomplished by reduced MI of terminal ileum in men(P<0.001)and women(P=0.030).In women,diarrhea was inversely associated with the MI of the jejunum(P=0.029),and constipation was positively associated with the MI of the terminal ileum(P=0.039).CONCLUSION Although MIs differ across diseases,a lower MI of the terminal ileum is mainly associated with male sex and an increased mural thickness.S
