摘　　要：目的 评价磁共振小肠造影对小肠疾病的诊断价值.方法 2013年1-7月,对北京朝阳医院临床怀疑小肠病变的53例患者（男/女=22/33例,中位年龄61岁）,行磁共振小肠造影（MRE）,评价MRE发现及诊断小肠病变的价值,同时对比分析MRE与胶囊内镜发现及诊断病灶的价值.结果 53例患者均完成MRE检查,MRE发现小肠异常31例.45例完成胶囊内镜检查,发现小肠异常30例.受试者工作特征曲线（ROC）显示MRE发现小肠病变的曲线下面积为90％,MRE诊断小肠病灶的曲线下面积为72.9％.MRE和胶囊内镜在发现小肠疾病中具有很好的一致性（x2=28.800,P =0.000）.结论 MRE对于小肠病变的发现很敏感,并有良好的正确诊断能力,具有较好的应用前景.Objective To evaluate the diagnostic value of magnetic resonance enterography （MRE）for small intestinal disease.Methods From January to July 2013,53 consecutive patients（male/female =22/31,median age =61 years） with suspected small intestinal disease were recruited.And the examinations of MRE and capsule endoscopy （CE） examinations were performed.Results MRE revealed 31 cases （31/53） and CE 30 cases （30/45） of small intestinal diseases.Receiver operating characteristic （ROC） curve revealed that the area under the curve （AUC） of MRE was 90% in detecting small intestine lesions and AUC of MRE was 72.9% in diagnosing small intestine lesions.There was a remarkable coherence of MRE and CE in detecting small intestine lesions （x2 =28.800,P =0.000）.Conclusion MRE is ideal for detecting and diagnosing small bowel disease.
