【摘要】 目的 探讨MRI对肝外梗阻性黄疸定位、定性诊断价值。方法 对117例肝外梗阻性黄疸病人行MRI平扫、增强扫描及MRCP,与手术病理或ERCP进行回顾性对照分析。结果 MRI平扫、增强扫描结合MRCP对肝外梗阻性黄疸定位诊断与最终诊断符合,符合率100.00%。定性诊断恶性肝外梗阻性黄疸符合率92.50%,结石性肝外梗阻符合率95.83%,非结石性肝外良性梗阻符合率79.31%。3组间符合率差异有统计学意义(P<0.05)。结论 MRI平扫、增强扫描结合MRCP对肝外梗阻性黄疸定位、定性诊断具有高特异性。更多还原

【Abstract】 Objective To investigate the diagnostic value of MRI extrahepatic obstructive jaundice.Methods 117 patients with extrahepatic obstructive jaundice were underwent conventional MRI,contrast-enhancement MRI and MR cholangiopancreatography(MRCP) examination.Their MRI and MPCP results were compared with endoscopic retrograde cholangiopancreatography(ERCP)and surgery results retrospectively.Results The correct niveau diagnosis rate of the extrahepatic obstructive jaundice by MRI and MRCP was 100.00%.The correct qualitative diagnosis rate for malignant obstruction,calculus obstruction and the benign obstruction except calculus obstruction was 92.50%,95.83% and 79.31% respectively.The diagnosis rates of three groups were significantly different(P<0.05).Conclusion MRI combined with MRCP play an important role in the diagnosis of extrahepatic obstructive jaundice.更多还原
