摘　　要：目的通过Meta分析比较超声造影(CEUS)和增强CT(CECT)对肝脏局灶性病变的诊断价值。方法检索PubMed和中国期刊网CNKI数据库关于CEUS及CECT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。结果CEUS诊断肝脏局灶性病变共纳入2041例,合并敏感度为89.00%,合并特异度为88.00%,加权SROC曲线下面积(AUC)为0.9666。CECT诊断肝脏局灶性病变共纳入686例,合并敏感度为93.00%,合并特异度为84.00%,加权SROC曲线下面积(AUC)为0.9610。结论CEUS与CECT对肝脏局灶性病变诊断准确性差异无统计学意义。Objective To compare the diagnostic value of contrast-enhanced ultrasound （CEUS） and contrast-enhanced computed tomography （CECT） for focal liver lesions. Methods PubMed and CNKI database were searched for English and Chinese language articles related to CEUS and CECT diagnosis for focal liver lesions. Data were analyzed with Metadisc software. Results A total of 2041 specimens were included in CEUS group and the sensitivity, specificity and the AUC of weighted summary receiver operating characteristic （SROC） curve was 89.00%, 88.00% and 0. 9666, respectively; 686 specimens were included in CECT group and the sensitivity, specificity and the AUC of weighted SROC curve was 93.00%, 84.00% and 0. 9610, respectively. Conclusion The accuracy of CEUS and CECT has no difference in diagnosis of focal liver lesions.
