Discover What’s New in BI-RADS® v2025 Manual

The illustrated BI-RADS® v2025 Manual is an extension of the 5th Edition of the BI-RADS Atlas. The BI-RADS manual provides standardized breast imaging terminology, report organization, assessment structure and a classification system for mammography, ultrasound and MRI of the breast. BI-RADS reporting enables radiologists to communicate results to the referring physician clearly and consistently, with a final assessment and specific management recommendations.

Through a medical audit and outcome monitoring, the system provides important mechanisms for peer review and quality assurance data to improve the quality of patient care. Standardized results permit maintenance and analysis of demographic and outcome data.

The BI-RADS manual includes:

  • Over 900 clinical images
  • Auditing and outcomes monitoring includes mammography, ultrasound and MRI
  • Updated breast composition descriptors
  • Guidance with FAQ for each section
  • New elasticity assessment descriptors for ultrasound
  • New breast implant descriptors for MRI

Since 1999, the interpreting physician has been required to send every patient who receives a mammogram a written mammography report expressed in terms easily understood by a lay person. Failure to comply with this reporting requirement will result in a citation by the FDA.

These sample lay report letters are provided for your convenience; you may use these as is, modify them, or create your own lay reports.

Use of an ACR-approved computer-based reporting software is required for participation in the ACR National Mammography Database (NMD).

The NMD Data Dictionary describes all of the data elements for the National Mammography Database, including whether or not a field is required and what responses are valid.
