The 5th edition of the Breast Imaging Reporting and Data System (BI-RADS) was published in December 2013. The MRI section of the lexicon has considerable changes compared with the prior BI-RADS lexicon. In this exhibit, the changes in parenchymal enhancement definitions and descriptors of foci, mass, and non-mass lesions will be reviewed. Example cases will be provided to allow the application of the new lexicon descriptors in a multiple choice fashion.
