摘　　要：目的探讨2D-MRCP、3D-MRCP及横断位、冠状位T2WI联合应用对低位胆道梗阻的诊断价值。方法收集我院近3年110例经磁共振检查(2D-MRCP、3D-MRCP及横断位、冠状位T2WI),并经临床诊断或手术病理证实为低位胆道梗阻病例,将影像诊断结果与临床、病理诊断结果进行回顾性对照分析。结果 2D-MRCP、3D-MRCP及横断位、冠状位T2WI联合应用对低位胆道梗阻定位诊断准确率为100.0%,定性诊断准确率为90.9%。结论 MRCP是胆道疾病无创性诊断的最佳选择,2D-MRCP、3D-MRCP及横断位、冠状位T2WI联合应用,对低位胆道梗阻的诊断具有极高的准确性,可为临床诊疗提供可靠依据。Objective To explore the value of 2D-MRCP and 3D-MRCP combined with axial and coronal T2WI in diagnosis of obstruction of lower biliary tract. Total 110 patients who received MRI examinations （2D-MRCP, 3D-MRCP, axial T2WI and coronal T2WI） and were definitely diagnosed with obstruction of lower biliary tract in clinical diagnosis or by operative pathology in our hospital in recent three years were selected. A retrospective contrast analysis was made on the results of imaging and pathologic diagnosis. The localization diagnosis accuracy of 2D-MRCP and 3D-MRCP combined with axial and coronal T2WI for＆amp;nbsp;obstruction of lower biliary tract was 100.0%, while the qualitative diagnosis acc uracy was 90.9%. MRCP is the best option for non-invasive diagnosis of biliary tract diseases. The accuracy of 2D-MRCP and 3D-MRCP combined with axial and coronal T2WI in diagnosis of obstruction of lower biliary tract is very high and can provide a reliable basis for the clinical diagnosis and therapy.
