摘要
目的 探讨磁共振胆胰管成像 (MRCP)对梗阻性黄疸的临床诊断价值。方法 对 36例结石、壶腹肿瘤、胰头癌、胆管癌及炎性狭窄等梗阻性黄疸病人进行术前MRCP检查 ,结合手术 ,回顾性评价术前MRCP定性及定位诊断。结果 (1)定位诊断 :对结石梗阻部位显示率为 10 0 % ,对其他梗阻部位显示率为 6 6 7%～ 10 0 % ;(2 )定性诊断 :术前诊断结石正确率为 76 9% ,恶性占位正确率为 33 3 %～ 6 6 7%。结论 MRCP对梗阻性黄疸疾病定位诊断准确 ,结合影像对结石定性诊断特异性较高 ,对肿瘤部位诊断结合其他辅助诊断方法会提高诊断率。
objective To evaluated the clinical diagnosis value of obstructive jaundice by magnetic resonance cholangiopancreatography(MRCP) imaging. Methods patients with choledocholithiasis, ampullar tumor, pancreatic head carcinoma, cholangiocarcinoma and inflammation were examined by MRCP.compared with results of operation ,looking back the evaluateion of qualitative and orientative diagnosis MRCP before operation . Results(1)The demonstrating rates of choledocholithiasis were 100.0%,and of others were 66.7%～ 100%. (2)Diagnosis of orientation of choledolithiasis were 76.9%,malignant obstruction were33.3%～ 66.7%.Conclusion MRCP can accurately define the obstructive site in obstructive disease. The specificity for the diagnosis of choledocholithiasis is very high when combining with resource images for analysis, but it specificity for the diagnosis of other diseases needs further research.
