Standardized terminology, report organization and assessment structure allows radiologists to communicate breast imaging findings with referring physicians in a clear and succinct manner. The much awaited American College of Radiology BI-RADS Atlas 5th edition was released in February 2014. Since the 4th edition was released more than 10 years ago, it may be difficult to remember all the specific changes in the 5th edition. While the majority of changes represent re-organization and consolidation of terms, there are also new descriptors in the lexicon. At the end of this educational exhibit the learner will: 1. Understand the changes to BI-RADS 5th edition. 2. Review those changes with imaging correlation on mammography, US and MRI. 3. Have an opportunity for self assessment with an interactive case review.

1. Introduction 2. History of BI-RADS 3. Overview of BI-RADS 5th edition on mammography, US and MRI 4. Review of ACR mammographic density 5. Imaging examples of all changes in BI-RADS 5th edition compared to 4th edition on mammography, US and MRI 6. Review of guidance chapter 7. Interactive multiple-choice case review testing the recent changes to BI-RADS 5th edition
