Could ultrasonic elastography help the diagnosis of breast cancer with the usage of sonographic BI-RADS classification?

•Our study is multi-center study at 8 different institutions from 3 geographic areas across China (North, South, and West).•This study reported the usefulness of strain elastography in combination with BI-RADS scoring system. Although we have several clinical studies suggesting that specificity may be improved by adding elastography to the scanning of breast masses and that the confidence level for malignancy will be improved, the present study revealed that elastography will contribute to BI-RADS greater for breast lesions <1cm in diameter and in <50 year group.
