Abstract：Objective To explore the diagnostic value of 3.0T magnetic resonance enterography (MRE)technology for active small bowel Crohn disease(CD).Methods A total of 23 inpatients suspected with active small bowel CD treated in Hainan People′s Hospital from January 2015 to January 2017 were given 3.0T MRE,Imaging features and signal characteristics of small bowel lesions scanned in different phases were analyzed.The results of pathological examination by enteroscopy were the gold standard,the sensitivity and specificity of the scanning method in diagnosing small bowel CD were analyzed.Results The MRI image features of small intestinal CD lesions were multiple segmental thickening and abnormal enhancement of intestinal wall,morphological fixation,signal elevation and heterogeneity,comb sign,intestinal stenosis or dilatation.There was no significant difference in signal intensity of small intestinal lesions in different phases,intestinal wall and lumen changes between plain scan and enhancement(P>0.05).The sensitivity of MRE in diagnosing small bowel CD was 100%,the specificity was 83.33%.The accuracy rate of MRE in diagnosis of small bowel CD was 95.65%,and there was no significant difference between MRE and enteroscopy (P>0.05).Conclusion The small bowel CD lesions have characteristic changes under MRE scanning.MRE can improve the accuracy rate of judging small intestinal CD,and the specificity needs to be further improved.
