摘　　要：目的:采用剪切波弹性成像(SWE)技术检测不同乳腺病灶的弹性模量值,评价SWE技术对乳腺良恶性病变的鉴别诊断价值。方法:选择2015-05~2016-12我院乳腺外科就诊的80例患者为研究对象,共计102个病灶。进行实时剪切波弹性成像检查,获得病灶的弹性模量值,包括最大值、最小值、平均值和标准差。BI-RADS为诊断分级标准。制作ROC曲线,分析SWE检测结果在诊断乳腺良恶性病变中的价值。结果:80例患者中诊断结果为良性的有48例,59个病灶;恶性的有32例,43个病灶。良、恶性病灶的弹性最大值、最小值、平均值和标准差比较,差异均具有统计学意义(P<0.05)。弹性最大值和弹性平均值的ROC曲线下面积(AUC)分别是0.821和0.911。弹性最大值敏感性、特异性和准确性分别是91.23%、92.10%、92.45%;弹性平均值敏感性、特异性和准确性分别是51.89%、89.32%、80.65%。结论:SWE技术对乳腺病灶的良、恶性诊断有较高的准确性、敏感性和特异性,具有重要的鉴别诊断价值。Objective：To evaluate the value of shear wave elastography（SWE）technology in the differential diagnosis of benign and malignant breast lesions by using SWE technology detect the different elastic modulus value of breast lesions.Methods：Eighty patients with breast surgery in our hospital were selected as the research object from May 2015 to December 2016,a total of 102 lesions.The elastic modulus value,including maximum,minimum,mean and standard deviation were detected by real-time shear wave elastic imaging.Breast imaging reporting and data system（BI-RADS）was used as standard of diagnosis and classification.The ROC curve was made,the SWE value in diagnosis of breast benign lesions was analyzed.Results：From 80 cases of patients with the diagnosis for benign in 48 cases,59lesions,malignant in 32 cases,43 lesions.There were statistically significant differences in elasticity of maximum,minimum,average and standard deviation（P0.05）between benign and malignant lesions.Elastic maximum and average area under the ROC curve（AUC）was 0.821 and 0.911,respectively.Sensitivity,specificity and accuracy of elastic maximum were 91.23%,92.10%,92.45%.Sensitivity,specificity and accuracy of elastic average were 51.89%,89.32%,80.65%.Conclusion：SWE technology in benign and malignant diagnosis of breast lesions with high accuracy,sensitivity and specificity,has important diagnostic value.
