Abstract: Objective To evaluate the detection rate of lesions of patients with Crohn’s Disease(CD)tusing combining the con-ventional MR and Cine MRE(MR enterography).Methods MRI images of twenty-nine patients with CD confirmed by clinic were analyzed retrospectively.Scan sequences include coronal Cine MRE,and standard MR protocol (FIESTA,SS-FSE,LAVA C+). Two radiologists analyzed the images with double blind method to explored whether there were significant differences existing be-tween having or having not Cine MRE on lesion detection rate (wall thickness,stenosis,comb sign,adhesions,fistulas).Results The number of lesions detected by standard MR combined with Cine MRE compared with standard MR alone were 82/80 (P =0.1 6) for wall thickening,52/43 (P =0.03)for stenosis,6/7 (P =0.36)for the comb sign,5/7(P =0.66)for adhesions,2/2for fistulas re-spectivily.Conclusion It is meaningless to combine Cine MRE with standard MR in lesions detection in patients with CD,Cine ima-ges can accurately determine diseased bowel stenosis,and show the adhesive location.On the basis of standard MR,Cine MRE can be added in patients with CD when necessary.
