摘　　要：目的探讨MR胆胰管成像(MR cholangiopancreatography,MRCP)和容积式插入法屏气检查(volume imaging body exam,VIBE)序列在梗阻性黄疸中定性诊断的价值。方法对119例梗阻性黄疸病人的MRCP结合MRI VIBE序列诊断与最终诊断[经皮穿刺胆道造影术(PTC)或内窥镜逆行性胰胆管造影术(ERCP)及手术、病理结果]进行回顾对照分析,评价MRI特殊序列对梗阻性黄疸定性诊断的价值。结果梗阻性黄疸MRCP和VIBE诊断与最终诊断的定性诊断符合率为94.1%;分类比较符合率为:结石性梗阻100.0%,除结石外良性梗阻83.9%,恶性梗阻94.3%。恶性梗阻组与除外结石良性梗阻组符合率的差异有统计学意义。结论MRI特殊序列对梗阻性黄疸定性诊断特异性较高。Objective To investigate the diagnostic value of MR cholangiopanereatography （MRCP） and volume imaging body exam （VlBE） in the obstructive jaundice. Methods 119 patients with obstructive jaundice underwent MRI examination of upper abdomen using the special sequences of MRCP and VIBE. The qualitative diagnosis of obstructive jaundice was evaluated with MRCP and VIBE in comparison with that of percutaneous transhepatie cholangiography （PTC） , endoscopic retrograde cholangiopanereatography （ERCP） and operation. Results The corresponding diagnostic rate was 94.1% for obstructive jaundice with MRCP and VlBE,of that the corresponding rate in cal- culus obstruction,malignant obstruction,and the benign obstruction except calculus obstruction was 100% ,94.3% and 83.9% respectively. There was significant difference between malignant obstruction and benign obstructive （ P 〈 0.05 ）. Conclusion MRI special sequences ineluding MRCP and VlBE are of significant value in diagnosing the obstructive iaundiee qualitatively.
