目的:探讨实时剪切波弹性成像(Shear-wave elastography,SWE)联合超声造影(Contrast-enhanced ultrasonography,CEUS)优化乳腺病变BI-RADS分类的价值.方法:对106例女性患者共108个乳腺病变进行SWE和CEUS检查,根据颜色六分法(Ecol)对病灶SWE彩色图像进行色彩评估,运用CEUS 5分法对病灶评分.根据SWE和CEUS结果优化BI-RADS分类.以手术病理结果为诊断金标准,构建受试者工作特征(Receiver operating characteristic,ROC)曲线,比较BI-RADS分类调整前后的曲线下面积(Area under curve,AUC).结果:BI-RADS分类调整前AUC为0.781,调整后AUC为0.898,两者有显著性差异(P＜0.05).结论:联合应用SWE与CEUS可以明显提高BI-RADS的诊断效能.%Objective:To assess the value of shear-wave elastography(SWE) combined with contrast-enhanced ultrasonography(CEUS) in improvement of breast imaging reporting and data system (BI-RADS) categorization.Methods:One hundred and six patients with 108 lesions were examined with SWE and CEUS respectively.Color assessments in SWE was performed using a six-point color score (Ecol),and 5-point scores were assessed for CEUS.A revised BI-RADS classification was assigned based on the combination of SWE and CEUS.The results were compared using the area under the receiver operating characteristic curve(AUC).Results:The AUC of BI-RADS and SWE+CEUS-based BI-RADS were 0.781,0.898,and significant difference was noted (P＜0.05).Conclusion:The combination of SWE and CEUS can significantly improve the diagnostic performance of BI-RADS.
