Abstract Objective: To explore the application value of real time shear wave elastography(RT-SWE) in the diagnosis of breast masses, and to provide new ideas for the differential diagnosis of breast masses. Methods: 500 cases of breast lumps treated in the First Affiliated Hospital of Xi’an Jiaotong University from January 2015 to February 2018 were included in this study. The RT-SWE technique was used to scan the various quadrants of the breast mass, taking the pathological results as the gold standard, the modulus of elasticity of benign and malignant masses was compared. Receiver operating characteristic(ROC) was plotted and the efficacy of RE-SWE in the diagnosis of breast lumps was analyzed, to explore its clinical application value. Results: 667 breast lesions were detected, including 408 benign masses and 259 malignant masses. The Emax, Emean, Emin, SD, ratio and shear wave velocities of benign tumors were all lower than those of malignant masses, the differences are statistically significant(P<0.05). Emean has the largest area under the curve(0.931), the diagnostic accuracy is 91.45% in discriminating the benign and malignant breast tumors, followed by the shear wave velocity, the area under the curve is 0.899, and the diagnostic accuracy is 89.81%. Conclusion: The Emean and shear wave velocity parameters of RT-SWE images can provide an objective reference for differentiating benign and malignant breast masses. It is worthy to be widely applied in the diagnosis of clinical breast masses.
