Abstract:

Objective To explore the values of real⁃time shear wave elastography（SWE）and/or contrast⁃ enhanced ultrasound（CEUS）techniques in the diagnosis of breast cancer. Methods One hundred and twelve breast tumor patients with a total of 112 breast masses hospitalized in our hospital from April 2015 to December 2018 were divided into benign mass group（n = 65）and malignant mass group（n = 47）according to the pathological examination results. SWE and CEUS were performed in both groups. The area under curve（AUC）of the receiver operating characteristic（ROC）was used to analyze the diagnostic values of SWE and/or CEUS for the breast masses. Results The average elasticity，maximum elasticity，peak intensity，and time of significant decline in the malig⁃ nant mass group were significantly higher than those in the benign mass group（P < 0.05），and the peak time was significantly lower than that of the benign mass group（P < 0.05）. There was no statistically significant difference in the minimum elasticity value between the two groups（P > 0.05）. The AUC of SWE and CEUS for breast cancer diagnosis were 0.766，0.818，0.896，respectively. Conclusion Both SWE and CEUS have certain diagnostic value when used alone in the diagnosis of breast cancer，and their combined application is conducive to improving the accuracy of diagnosis.
