Abstract 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.
