中文摘要: 目的探讨声触诊弹性成像（STE）、声触诊弹性测量（STQ）及天门冬氨酸氨基转移酶与血小板比率指数（APRI）、基于4因子的纤维化指数（fibrosisindexbasedonthefourfactors,FIB-4指数）对慢性肝病纤维化的诊断效能及与病理的相关性。
方法选取2018年8月至2022年2月昆明市第一人民医院收治的符合研究条件的患者80例，行肝脏穿刺活检，穿刺前行STE、STQ检查得出肝硬度值（LSMSTE、LSMSTQ）中位数，收集肝穿刺活检前7d内的血清学指标，计算APRI和FIB-4，与肝脏穿刺活检病理结果对照，以病理结果为“金标准”，绘制F2期、F3期、F4期的LSMSTE、LSMSTQ和APRI、FIB-4诊断肝纤维化的受试者工作特征曲线（ROC），并计算曲线下面积（AUC）及各期敏感度、特异度，AUC采用Delong法进行比较。应用Spearman相关系数评估LSMSTE、LSMSTQ、APRI、FIB-4与病理分期之间的相关性。
结果LSMSTE、LSMSTQ、APRI和FIB-4诊断慢性肝病肝纤维化的AUC分别为0.863、0.840、0.693、0.805;AUC比较发现，F2期、F3期、F4期LSMSTE、LSMSTQ诊断效能相当（P＞0.05）;F2期、F4期LSMSTE、LSMSTQ均优于APRI(P＜0.05)，与FIB-4诊断效能相当(P＞0.05);F3期LSMSTE、LSMSTQ、FIB-4优于APRI（P＜0.05）。LSMSTE诊断肝纤维化F2期、F3期、F4期的敏感度分别为80.0%、63.2%、81.3%，特异度分别为80.0%、83.3%、82.8%;LSMSTQ诊断肝纤维化F2期、F3期、F4期的敏感度分别为71.7%、76.3%、75.0%，特异度分别为90.0%、69.0%、93.7%。相关性分析结果显示，LSMSTE、LSMSTQ、FIB-4及APRI与肝纤维化程度分别呈正相关（r=0.630、0.646、0.470、0.293，P<0.05）。
结论LSMSTE、LSMSTQ、APRI及FIB-4均可用于临床评估慢性肝病肝纤维化程度，但剪切波弹性成像LSMSTE、LSMSTQ诊断效能明显优于血清学诊断模型APRI、FIB-4。
