摘　　要：目的探讨实时超声弹性成像(RTE)与声触诊定性弹性成像(VTI)在肝脏局灶良恶性病变中的诊断价值及二者诊断的一致性。方法回顾性分析2014年12月至2016年12月收治的肝脏局灶良恶性病变60例(66个肝内结节)患者的临床病理及超声影像资料。以手术或肝穿刺病理结果为标准,计算彩色超声仪RTE和VTI两种成像方法对肝内结节诊断的敏感度、特异度;绘制受试者工作特征(ROC)曲线,判断其诊断价值,对比两种方法诊断的一致性。结果 RTE诊断肝脏局灶良恶性性病变的敏感度、特异度分别为88.57%、77.42%;VTI诊断的敏感度、特异度分别为77.14%、70.97%;RTE与VTI诊断效能的ROC曲线下面积分别为0.79、0.77,两者对肝脏局灶性病变诊断效能的比较无统计学差异差异(Z=0.52,P>0.05)。Kappa检验显示,两种成像方法有较好的诊断一致性(Kappa=0.07、0.11,P均>0.05)。结论彩色超声RTE与VTI在肝脏局灶良恶性病变中具有较高的诊断价值及一致性。Objective To investigate the value of real-time elastography（ RTE） and virtual touch tissue imaging（ VTI）in the diagnosis of liver focal lesions,and compare the consistency between the two methods. Methods The clinicopathologic and ultrasonographic data of 60 patients with iver focal lesions（ a total of 66 intrahepatic nodules） from December 2014 to December 2016 were retrospectively analyzed. The pathology results of surgery or liver puncture was taken as the standard,and the sensitivity and specificity of RTE and VTI of intrahepatic nodules were calculated. The receiver operating characteristic curve（ ROC） was drawn to judge the diagnostic value and to compare the consistency of the two methods. Results The sensitivity and specificity of RTE in diagnosis of liver lesions were 88. 57% and 77. 42%,respectively. And the sensitivity and specificity of VTI were 77. 14% and 70. 97%,respectively. The area under the ROC of RTE and VTI were 0. 79 and 0. 77,respectively. There was no significant difference in the diagnosis of liver focal lesions between the two methods（ Z = 0. 52,P 〉0. 05）. The Kappa test showed that the two methods had a good diagnostic consistency（ Kappa = 0. 07,0. 11,P 〉0. 05）. Conclusion RTE and VTI have a high diagnostic value and consistency in the diagnosis of focal hepatic lesions.
