摘　　要：目的探讨常规磁共振平扫结合DWI序列对于肠梗阻良、恶性病因的诊断价值。方法分析我院收治的经手术病理证实的89例肠梗阻磁共振常规平扫结合DWI序列成像资料,其中良性梗阻44例,恶性梗阻45例;评价磁共振成像对肠梗阻病因的良恶性判定价值以及良恶性梗阻病因的诊断符合率。结果常规磁共振结合DWI对于89例肠梗阻的定位诊断符合率100%,病因诊断符合率82.0%(73/89);对肠梗阻病因的良、恶性判定符合率为97.8%(87/89),对良、恶性肠梗阻的病因诊断符合率分别为72.7%(32/44)和91.1%(41/45),二者差异具有统计学意义(2=5.10,P=0.024<0.05)。结论常规MRI结合DWI序列对肠梗阻致病因素的良恶性具有较高的诊断价值,可以作为肠梗阻病因尤其是恶性病因的重要检查手段。Objective To investigate the diagnostic value of MRI routine scan combined with DWI in the etiology of be- nign and malignant bowel obstruction. Methods We analyzed the data of MRI routine scan combined with DWI of 89 cases of bowel obstruction by operation and pathology, including 44 cases of benign bowel obstruction, 45 cases of malignant bowel obstruction, evaluated the judging value of benign and malignant, and evaluated the coincidence rate of the etiology of benign and malignant bowel obstruction. Results The MRI positioning diagnostic accuracy rate of 89 cases of bowel ob- struction was 100%, the etiology diagnostic accuracy rate of 89 cases of bowel obstruction was 82.0% （73/89）. The jud- ging accuracy rate of benign and malignant was 97.8% （87/89）, the etiology diagnostic accuracy rate of benign and malig- nant obstruction was 72.7% （32/44） and 91.1% （41/45）, there was significant difference （χ^2 = 5.10, P = 0. 024〈0.05）. Conclusion MRI has a high diagnostic value for differential diagnosis of benign and malignant bowel obstruction, and plays an important role in diagnosing bowel obstruction, especially in the malignant obstruction.
