摘　　要：目的评价MRI在肠梗阻病因诊断中的应用价值。资料与方法应用MRI对临床拟诊为肠梗阻的39例患者进行检查,分析梗阻病因,并与手术或随访结果对照。结果39例中有36例经手术证实,其中肿瘤所致梗阻25例,粪石、胆石梗阻4例,肠粘连4例,乙状结肠扭转3例。MRI术前定性诊断准确35例,1例小肠肿瘤误诊为炎症。梗阻部位在小肠者11例,在结肠者25例,MRI定位与手术一致。3例未手术者MRI诊断为粘连性肠梗阻,经保守治疗后缓解。MRI定性与定位诊断符合率分别为97%和100%。结论MRI可以较为准确地诊断肠梗阻病因及其梗阻部位,为临床制订治疗方案提供重要信息。Objective To evaluate the value of MRI in the diagnosis of intestinal obstruction. Materials and Methods 39 patients suspected intestinal obstruction were performed MRI examination. MRI findings were compared with surgery or clinical follow up data. Results 36 of 39 cases were proved by post surgical pathology, including neoplasms （25 cases）, feces or gallstone ileus（4 cases）, adhesions（4 cases） and torsion（3 cases）. MRI diagnosesed correctly in 35 cases before surgery, only one, neoplasms was misdiagnosed. The location of intestinal obstruction on MRI was correspongding with surgery. Compared with histopathology and operation, the coincidence of qualitation and localization on MR were 97% ,100% respectively. Conclusion MRI can correctly display the causation and location of intestinal obstruction, which provide more information for clinical treatment.
