摘　　要：目的通过循证医学分析超声造影(CEUS)和增强磁共振(CEMRI)对肝脏局灶性病变的诊断价值。方法检索Pubmed、Cochrane library、中国生物医学文献数据库以及CNKI数字图书馆关于CEUS及CEMRI诊断肝脏局灶性病变的中英文文献,并对文献进行评价和筛选。应用Metadisc软件对纳入的试验结果进行分析,比较CEUS和CEMRI对肝脏局灶性病变的诊断价值。结果符合条件的文献共43篇,CEUS诊断肝脏局灶性病变合并敏感度为89%,合并特异度为90%,加权SROC曲线下面积(AUC)为0.9656。CEMRI诊断肝脏局灶性病变合并敏感度为79%,合并特异度为84%,加权SROCAUC为0.8956。结论 CEUS与CEMRI对肝脏局灶性病变诊断准确性无统计学差异。Objective To compare the diagnostic value of contrast-enhanced ultrasound（CEUS）and contrast-enhanced MRI（CEMRI）for focal liver lesions using evidence-based medicine.Methods Articles written in Chinese or English which are related to the diagnosis of focal liver lesions by CEUS and CEMRI were retrieved in databases,including PubMed,Cochrane library,CBM,and CNKI.The retrieved articles were evaluated and selected.Data were pooled by Metadisc software.Results Totally 43 articles were analyzed.The pooled sensitivity,specificity,and AUC of weighted summary receiver operating characteristic curve（SROCC）curve were 89%,90%,and 0.9656 for articles related to CEUS and 79%,84%,and 0.8956 for articles related to CEMRI,respectively.Conclusion The accuracies of CEUS and CEMRI are similar in diagnosing focal liver lesions.
