3D-MRCP与Balance-FFE及常规MRI序列联合应用诊断梗阻性黄疸

摘要

Objective To evaluate the value of 3D-MRCP, Balance-FFE combined with routine MRI examination in the diagnosis of obstructive jaundice. Methods The MRI exams of 156 patients with obstructive jaundice proved by operation were analyzed. Results The study participants were classified into 3 groups; stone disease into group Ⅰ, tumor into group Ⅱ and others into group Ⅲ. 3D-MRCP, Balance_FFE combined with routine MRI examination had 100%, 80. 3% .and 100% corresponding diagnostic rates in group Ⅰ, group Ⅱ , group Ⅲ respectively. The total corresponding diagnostic rate was 92. 9%. Conclusion By analyzing the direct signs and indirect signs, 3D-MRCP, Balance-FFE combined with routine MRI examination can improve the diagnostic accuracy of obstructive jaundice.%目的 评价3D-Magnetic Resonance Cholangiopancreatography(MRCP)与Balance fast field echo(BalanceFFE)及常规MRI序列联合应用对梗阻性黄疸的诊断价值.方法 156例梗阻性黄疸患者行包括3D-MRCP、冠状位BFFE、抽位TIWI、T2WI、T2压脂,部分行同层动态增强检查.所有影像诊断结果与最终手术病理结果进行回顾对照分析.结果 156例病人分为3组,组Ⅰ结石94例,组Ⅱ肿瘤56例,组Ⅲ其它6例.3D-MRCP、B-FFE与常规MRI联合应用,定性诊断的符合率分别为100％、80.3％和100％,总符合率为92.9％.结论 3D-MRCP、B-FFE与常规MRI扫描序列联合应用通过观察直接征象和间接征象,对梗阻性黄疸的定性诊断有较高准确性.
