February 5, 2014 — Breast imagers worldwide now have access to the fifth edition of the American College of Radiology (ACR) Breast Imaging Reporting and Data System (BI-RADS) Atlas. This edition is designed to improve patient care by serving as a comprehensive guide providing standardized breast imaging terminology, report organization, assessment structure and a classification system for mammography, ultrasound and magnetic resonance imaging (MRI) of the breast.
The illustrated atlas contains more than 700 clinical images and numerous charts, tables and diagrams. A section on follow-up and outcome monitoring includes auditing procedures and benchmarks applicable to all three breast imaging modalities. In addition, the fifth edition includes updated descriptors for breast composition, descriptors for elasticity assessment in ultrasound and descriptors for implant assessment in MRI.
“The new edition of BI-RADS is truly a compendium of information and experience for breast imaging reporting and auditing. It is designed for everyday practice and will help providers issue clear breast imaging reports and meaningfully evaluate their performance,” said Carl J. D’Orsi, M.D., FACR, chair of the American College of Radiology Committee on BI-RADS.
The fifth edition of BI-RADS is the culmination of years of collaborative efforts from the ACR BI-RADS committee and subcommittee members.
