Standardized diagnosis and reporting of breast cancer.

Standardized terminology developed by the American College of Radiography (ACR) through the Breast-Imaging Reporting and Data System (BI-RADS) lexicon is used worldwide to describe the findings of the various breast-imaging techniques (mammography, ultrasound, and magnetic resonance imaging (MRI)). A 7-level positive predictive value (PPV) of malignancy classification system (from BI-RADS category 0 to category 6) has been based on this terminology, giving imaging a central role in the diagnostic strategy. This document presents the standardized, compulsory BI-RADS terminology used in breast-imaging reports in 2013 in view of the new edition that will be published at the end of the year.
