Abstract:Objective To evaluate the application value of different kinds of elastic modulus value
computed by shear wave elastrography (SWE) technology in differentiating benign and malignant breast
solid lesions. Methods SWE technology was performed in 156 cases of breast solid lesions to detect
the elastic modulus value including the elastic modulus maximum (Emax), the average elastic modulus
(Emean), the elastic modulus distribution of quantitative indicators (Esd), and the ratio between the Emax of
breast solid lesion and the Emax of normal breast tissue (Eratio). The diagnosing boundary value of the four
different data was calculated respectively. Results The elastic modulus value of breast solid lesions were
statistically significant, including Emax, Emean, Esd, and Eratio. As the ROC curve displayed, when the Youden
index reached the maximum, the sensitivity of Emax, Emean, Esd, and Eratio were 82.2%, 74.4%, 83.3%, and
85.7%; the specificity of Emax, Emean, Esd, and Eratio were 96.8%, 90.4%, 93.4%, 95.1%. Conclusion The
elastic modulus value of breast solid lesions is of great significance in the evaluation and differential
diagnosis of benign and malignant breast solid lesions. Contrasted with the other elastic modulus value,
the Eratio and the Emax have greater diagnostic value.
