摘　　要：目的探讨剪切波弹性成像(SWE)对乳腺病变的诊断价值。方法选取收治的疑似乳腺癌患者126例作为研究对象,术前均进行SWE检查,以病理结果作为金标准,分析SWE对乳腺病变良恶性的诊断效能。结果经病理诊断乳腺良性病变79例,恶性病变47例;SWE定性分析预测乳腺病变良恶性的灵敏度、特异度、准确度分别为:91.49%、87.34%、88.89%;良恶性组间的各参数(Emax、Emin、Emean、SD和Eratio)的差异均有统计学意义(P<0.01);各定量参数判断良恶性的灵敏度、特异度、准确度分别在85.10%~95.14%、79.75%~89.87%、84.92%~91.26%范围,其中以参数Emax的诊断效能最佳,ROC曲线的AUC为0.96,灵敏度、特异度、准确度分别为95.74%,88.61%,91.26%;Emin的诊断效能最低,ROC曲线的AUC为0.82,其诊断灵敏度、特异度、准确度分别为85.10%、79.75%、84.92。结论剪切波弹性成像定性和定量方法在判断乳腺病变良恶性均有较高的诊断价值。Objective To investigate the diagnostic value of shear wave elastography(SWE)in breast lesions.Methods 126 suspected breast cancer patients were selected.All patients underwent SWE examination before operation.The diagnostic efficacy of SWE for breast lesions was analyzed based on the pathological results as the gold standard.Results 79 cases of benign breast lesions and 47 cases of malignant breast lesions were diagnosed by pathology.The sensitivity,specificity and accuracy of SWE qualitative analysis in predicting benign and malignant breast lesions were 91.49%,87.34%and 88.89%,respectively.There were significant differences in quantitative parameters(Emax,Emin,Emean,SD and Eratio)between benign and malignant groups(P<0.01).The specificity and accuracy ranged from 85.10%to 95.14%,79.75%to 89.87%,84.92%to 91.26%respectively.Among them,the diagnostic efficiency of parameter Emax was the best.The AUC of ROC curve,sensitivity,specificity and accuracy were 0.96,95.74%,88.61%and 91.26%respectively.The diagnostic efficiency of Emin was the lowest,and the AUC of ROC curve,diagnostic sensitivity,specificity and accuracy were 0.82,85.10%,79.75%,84.92%respectively.Conclusion Qualitative and quantitative methods of shear wave elastography are of high diagnostic value for benign and malignant breast lesions.
