MRCP结合薄层T2WI对胆总管胰腺段小结石的诊断价值

摘要

Objective To discuss the value of thin-slice T2WI MRI with MR Cholangiopancreatography in the diagnosis of the pancreatic segment of mini bile duct cholelithiasis. Methods A retrospective analysis was performed to the 87 cases diagnosed as bile duct mini cholelithiasis based on MRCP to assess the value of thin-slice T2WT MRI in these cases. Results Seventy-eight cases had coincidence of 89.7% with ERCP or pathological findings, with 3 cases of missed diagnosis and 6 cases of misdiagnosis. Conclusion MRCP combined with thin-slice T2WI, being accurate and noninvasive, plays an important role in diagnosis of bile duct mini cholelithiasis. There is statistical difference between MRCP and MRCP combined with thin-slice T2WI.%目的:探讨MRCP结合轴位T2WI薄层对胆总管胰腺段小结石的诊断价值.方法:回顾性观察87例MRCP考虑胆总管胰腺段微小结石(长径≤5 mm,包含泥沙样结石)的MRI表现,结合轴位T2WI薄层进行分析.结果:23例结合轴位T2WI后排除,64例结合轴位T2WI后考虑小结石,与ERCP或手术结果对照,78例诊断符合,符合率约89.70%,3例漏诊,6例误诊.结论:MRCP结合轴位T2WI薄层对胆总管胰腺段有无小结石具有重要的诊断价值,是准确、无创的方法,增加T2WI薄层前后诊断符合率差异有统计学意义.
