摘　　要：目的探讨MRCP在梗阻性黄疸中的诊断价值。方法对75例梗阻性黄疸患者行MRCP检查,原始图像作三维重建,然后分析其影像表现及诊断结果,并与US、CT和直接胰胆管造影进行比较,对照手术病理结果进行分析。结果本组75例中MRCP确诊71例,误诊4例,确诊率95%,与直接胰胆管造影(92%)相近,明显高于US(74%)和CT(75%)。MRCP对梗阻性黄疸定位诊断准确率为100%。结论MRCP作为无创性检查技术,完整清晰地显示胰胆管系统结构,提高了梗阻性黄疸的定位和定性诊断率,为临床保守或手术治疗提供可靠依据,可作为梗阻性黄疸患者的首选影像学检查方法。Objective To evaluate diagnostic value of MR cholangiopancreatography(MRCP)in obstructive jaundice.Methods MRCP was performed in 75 patients with obstructive jaundice.The source images were three dimensional reconstructed postprocessed on workstation.The findings of MRCP images were analyzed and compared with US,CT,direct cholangiography,surgery and pathology.Results The diagnostic accuracy of MRCP was 95 %approaching direct cholangiography (92 %),but it was superior to US (74 %)and CT (75 %)(P< 0.05).The accuracy of MRCP in evaluating the site of obstruction was 100 %.Conclusion MRCP is a noninvasive technique with excellent accuracy in the diagnosis of biliary obstructions and their causes, and is helpful to provide useful information for clinical surgical therapy or palliative drainage procedures.MRCP may provide one efficient alternative to direct cholangiopancreatography,especially when ERCP and PTC are unsuccessful or inadequate.
