摘　　要：目的探讨剪切波弹性成像(SWE)技术在BI-RADS 4类乳腺结节中的诊断价值。方法对已行常规超声检查且诊断为BI-RADS 4类的164个乳腺结节行SWE检查,测定其弹性模量Emax值及Eratio值,并计算其诊断临界值。结果乳腺良恶性结节的弹性模量Emax值及Eratio值差异均有统计学意义。通过ROC曲线分析,Emax值及Eratio值取诊断临界值66.9kpa、3.88时,其敏感性分别为为87.8%、92.9%,特异性分别为87.7%、96.0%。结论剪切波弹性成像技术对BI-RADS 4类乳腺结节的良恶性鉴别诊断具有重要诊断价值。Objective To evaluate the value of shear wave elastography in diagnosing BI-RADS 4 breast lesions.Methods One hundred and sixty-four breast nodules of BI-RADS 4 breast lesions were examined by conventional ultrasonic and shear wave elastography,and their elastic modulus Emax and ERatio values were determined,and their diagnostic threshold was calculated.Results The elastic modulus value of breast lesions were statistically significant,including Emax and Eratio.As the ROC curve displayed,The diagnosing boundary value of Emax and Eratio was 66.9kpa and 3.88,respectively.The sensitivity of Emax and Eratio were 87.8%and 92.9%,and the specificity of Emax and Eratio were 87.7%and 96.0%.Conclusion Shear wave elastography plays more important role in the differential diagnosis of BI-RADS 4 breast lesions.
