Breast Imaging Reporting and Data System
a. BI-RADS is an acronym for Breast Imaging-Reporting and Data System, a quality assurance tool originally designed for use with mammography. The system is a collaborative effort of many health groups but is published and trademarked by the American College of Radiology (ACR).
b. The system is designed to standardize reporting, and is used by medical professionals to communicate a patient's risk of developing breast cancer. The document focuses on patient reports used by medical professionals, not "lay reports" that are provided to patients.
c. The assessment categories were developed for mammography and later adapted for the MRI and Ultrasound Atlases. The summary of each category, given below, is identical for all 3 modalities.
d. Category 6 was added in the 4th edition of the Mammography Atlas.
e. BI-RADS Assessment Categories are:
2: Benign finding(s)
3: Probably benign
4: Suspicious abnormality
5: Highly suggestive of malignancy
6: Known biopsy – proven malignancy
