【摘要】 目的探讨磁共振胰胆管成像(magnetic resonance cholangiopancreatography,MRCP)对恶性梗阻性黄疸的诊断价值,提高MRCP对恶性梗阻性黄疸的诊断准确性。方法总结80例恶性病变致梗阻性黄疸的MRCP及常规MRI(磁共振成像)的影像学特征,将MRCP诊断结果与手术病理检查结果进行对照,分析MRCP诊断的准确性及各种恶性梗阻性黄疸MRCP的特征性表现。结果 MRCP对恶性梗阻性黄疸的定位诊断及梗阻近端胆管显示率为100.0%;对恶性梗阻性黄疸的的诊断准确率为83.8%,定位、定性诊断特异性高。结论 MRCP对恶性梗阻性黄疸的定位诊断准确率达100.0%;在定性诊断中有重要地鉴别诊断价值;能明显提高对恶性梗阻性黄疸的诊断准确率。更多还原

【Abstract】 Objective To investigate the value of MRCP in the diagnosis of malignant obstructive jaundice.Methods MRI and MRCP of 80 cases with obstructive jaundice by malignant disease were analyzed retrospectively.Diagnosis on MPCP were contrasted with pathology-based diagnosis.The findings and accuracy of MRCP-based diagnosis of malignant obstructive jaundice were analyzed.Results The positive rate of the orientation diagnosis and the detection rate of bile ducts on the proximal side of obstruction was 100.0%.The diagnostic accuracy of malignant obstruction was 83.8%.MRCP was found to have highly diagnositic specificity for determining the location and quality of obstruction.Conclusion MRCP have significance for clinical diagnosis of malignant obstructive jaundice.The diagnostic accuracy of MRCP for malignant obstructive jaundice was remarkadly higher.更多还原
