文摘目的:采用Meta分析的方法系统评价声辐射力脉冲成像(acoustic radiation force impulse imaging,ARFI)对非酒精性脂肪性肝病(nonalcoholic fatty liver disease,NAFLD)的诊断价值.方法:检索PubMed、Medline、Web ofScience、CNKI、WanFang Data、CBM、Google学术搜索,及追溯参考文献收集相关文献.根据纳入与排除标准筛选文献,采用QUADAS工具评估文献质量并提取数据.采用MetaDisc1.4、STATA12.0软件进行异质性分析,计算合并敏感度、特异度、阳性似然比、阴性似然比等指标,并绘制总受试者工作特征曲线(summary receiver operating characteristics,SROC),最后进行敏感性分析及发表偏倚的评估.结果:共8篇研究纳入本评价研究.Meta分析结果显示ARFI对NAFLD的合并敏感度和特异度分别为90%(95%CI:86%-94%)、78%(95%CI:73%-83%),合并阳性似然比及阴性似然比分别为3.57(95%CI:2.19-5.81)、0.13(95%C I:0.09-0.20),合并诊断比值比35.87(95%CI:19.96-64.48).SROC曲线下面积为0.9326,SE=0.0169,总诊断精确度Q*指数为0.8683.结论:ARFI具有较高的诊断效能,可作为诊断N A F L D的一种相对可靠、安全的无创诊断工具.
