1、现代生物医学进展wwwashengwuyixue.comProgressinModernBiomedicineVoL14NO.7MAR.2014·1279·doi:10.13241/j.cnki.pmb.2014.07.019瞬时弹性成像对慢性乙肝肝纤维化诊断的研究木徐燕李桂明薛芳冯艳玲施裕新△(上海市公共卫生临床中心医学影像科上海201508)摘要目的:探讨瞬时弹性成像(FibroScan)诊断慢性乙型肝炎肝纤维化的准确性。方法:选取慢性乙型肝炎患者289例,其中未做病理组198例,病理组91例,正常对照50例,病理组患者行病理肝纤维化检测,未做病理组患者检查B超,全
2、部患者及正常对照应用FibroScan进行肝脏硬度检测(1iverstifnessmeasurement,LSM)值测量。分析未做病理组慢乙肝组与正常对照组间及未做病理纽陉乙肝组B超肝纤维化各级间LSM值的差异;病理慢乙肝组采用受试者工作特征(ReceiverOperatingharacteristic,ROC)曲线分析FibroScan诊断肝纤维化的准确性,并得出各期诊断界值;根据该诊断界值对未做病理慢乙肝组进行FibroScan肝纤维化分期,分析其与B超肝纤维化分级的一致性。结果:LSM值在未做病理慢乙肝组和正常对照组间及B超肝纤维化各级间差别显著(P<0.05);
3、其中病理组统计结果显示F1、F2、F3、F4期肝纤维化的R0C曲线下面积(AreaunderReceiverOperatingCharacteristic,AUROC)分别为0.726、0.847、0.806、0.864,诊断界值分别为6.5、7.4、10.1、17.0kPa,敏感性分别为69.62%、68.33%、66.67%、72.22%,特异性分别为66.67%、87.10%、85.71%、91.78%;肝纤维化的FibroScan分期和B超分级具有一致性(Kappa值=0.366。P<0.05)。结论:FibroScan对慢性乙型肝炎肝纤维化尤其是严重肝纤维化及
4、肝硬化诊断准确性高,具有良好的临床应用价值。关键词:慢性乙型肝炎;肝纤维化;瞬时弹性成像中图分类号:R445.1。R575.2文献标识码:A文章编号:1673—6273(2014)07—1279-04StudyofFibroScanonDiagnosisOfLiverFibrosisinPatientswithChronicHepatitisB术xuYan,LIGui-m&g,XUEFang,FENGYan-ling,SH1Yu·Xin(DepartmentofMe&'calImaging,PublicHealthClinicalCenterAffiliatedtoFu
