目的:探讨磁共振胰胆管成像(M RCP)对恶性梗阻性黄疸疾病的诊断价值。方法:回顾性分析21例经手术及病理证实的恶性梗阻性黄疸患者常规M R I及M RCP检查影像资料。结果:本组中胆管癌11例,壶腹癌3例,胰头癌7例。M RCP能清晰地显示胰胆管树结构,能直观地显示胰胆管扩张和梗阻的部位、形态、范围,对梗阻性胆道疾病的定位诊断准确率为100%,定性诊断准确率为91%。结论:M RCP对恶性梗阻性黄疸定位诊断准确,定性诊断有较高特异性,为临床手术方案提供可靠依据。
Objective: To investigate the value of magnetic resonance cholangiopancreatography (M RCP) in the diagnosis of malignant obstructive jaundice. Methods: A retrospective analysis of 21 cases of malignant obstructive jaundice confirmed by surgery and pathology in patients with conventional M R I and M RCP examination of imaging data. Results: This group of 11 cases of cholangiocarcinoma, ampulla carcinoma in 3 cases, pancreatic cancer in 7 cases. M RCP can clearly show the structure of pancreaticobiliary duct, and can directly display the site, shape and extent of pancreaticobiliary duct dilatation and obstruction. The accuracy of localization diagnosis of obstructive biliary disease is 100% and the diagnostic accuracy of qualitative diagnosis is 91%. Conclusion: M RCP is accurate and accurate for the diagnosis of malignant obstructive jaundice, and provides a reliable basis for clinical operation.
