摘　　要：目的评估磁共振胰胆管造影技术(MRCP)及CT在肝外胆管微小结石中的诊断价值。方法回顾性分析2016年5月至2018年9月在本院治疗的95例疑似肝外胆管微小结石患者的CT与MRCP的检查结果,比较两种检查方式诊断结果、特异度、准确率及对不同部位胆总管微小结石的诊断结果。结果MRCP对胆管微小结石检出率(73.7%)高于CT检查结果(46.3%),差异有统计学意义(P<0.05);MRCP检查敏感度(94.4%)、特异度(91.3%),准确率(93.7%)、阴性预测值(84.0%)等指标均高于CT检测结果(P<0.05);MRCP对于肝总管、胆总管部位阳性符合率高于CT检查(P<0.05)。结论MRCP在肝外胆道微小结石诊断中的检出率、特异性、敏感度显著高于CT检查,对不同部位微小结石也有明显的鉴别诊断作用,且具有无创、不受梗阻影响、易于操作等优势,是临床肝外胆道微小结石的有效诊断方式。Objective To evaluate the diagnoses value of Magnetic resonance cholangiopancreatography and CT for the liver bile duct small calculus.Methods The CT and MRCP findings of 95 patients with suspected extrahepatic bile duct microlithiasis treated in our hospital from May 2016 to September 2018 were retrospectively analyzed,and the diagnostic results,specificity,accuracy and diagnostic results between the two examination modes for common bile duct microlithiasis at different locations were compared.Results The detection rate of minimal bile duct stones by MRCP(73.7%)was higher than that by CT(46.3%),the difference was statistically significant(P<0.05).The sensitivity(94.4%),specificity(91.3%),accuracy(93.7%)and negative predictive value(84.0%)of MRCP were higher than those by CT(P<0.05);the positive coincidence rate of MRCP for common hepatic duct and common bile duct was higher than that of CT(P<0.05).Conclusion The detection rate,specificity and sensitivity of MRCP in the diagnosis of extrahepatic bile duct microlithiasis are significantly higher than those of CT examination,and it also has obvious differential diagnosis effect for different parts of microlithiasis,and has advantages of noninvasive,not affected by obstruction,easy operation,etc.,which is an effective diagnostic method for clinical extrahepatic bile duct microlithiasis.
