Objective

To evaluate the diagnostic performance of shear-wave elastography SWE for the differential diagnosis of breast papillary lesions.

Methods

This study was an institutional review board-approved retrospective study, with a waiver of informed consent. A total of 79 breast papillary lesions in 71 consecutive women underwent ultrasound and SWE prior to biopsy. Ultrasound features and quantitative SWE parameters were recorded for each lesion. All lesions were surgically excised or excised using an ultrasound-guided vacuum-assisted method. The diagnostic performances of the quantitative SWE parameters were compared using the area under the receiver operating characteristic curve AUC.

Results

Of the 79 lesions, six 7.6% were malignant and 12 15.2% were atypical. Orientation, margin, and the final BI-RADS ultrasound assessments were significantly different for the papillary lesions p < 0.05. All qualitative SWE parameters were significantly different p < 0.05. The AUC values for SWE parameters of benign and atypical or malignant papillary lesions ranged from 0.707 to 0.757 sensitivity, 44.4–94.4%; specificity, 42.6–88.5%. The maximum elasticity and the mean elasticity showed the highest AUC 0.757 to differentiate papillary lesions.

Conclusion

SWE provides additional information for the differential diagnosis of breast papillary lesions. Quantitative SWE features were helpful to differentiate breast papillary lesions.
