BI-RADS 4 breast lesions: could multi-mode ultrasound be helpful for their diagnosis?

摘要

BackgroundThe malignant probability of Breast Imaging Reporting and Data System (BI-RADS) 4 breast lesions is 3–94%, which is a very large span, and thus leads to a high rate of unnecessary biopsy. Therefore, the differential diagnosis of benign and malignant BI-RADS 4 breast lesions has become extremely important. Thus, in this paper, we investigated the diagnostic value of conventional ultrasonography (US), contrast-enhanced ultrasound (CEUS) and shear wave elastography (SWE) for BI-RADS 4 breast lesions, and tried to figure out a multi-mode ultrasonic method for them.
