Focal breast lesion characterization according to the BI-RADS US lexicon: role of a computer-aided decision-making support
The breast imaging-reporting and data system (BI-RADS) lexicon was first developed in 2003 by the American College of Radiology (ACR), in an attempt to standardize image interpretation, reporting and teaching breast imaging, including ultrasound (US) [1]. Despite this validation, the variability in the assessment of focal breast lesions (FBLs) with the use of BI-RADS US lexicon is still an issue, in particular for some of the descriptors, such as margin and echo pattern of lesion.
