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).

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.

The BI-RADS is published by ACR in the form of the BI-RADS Atlas. As of 2007 the Atlas is divided into 3 publications:

Assessment Categories

While BI-RADS is a quality control system, in day-to-day usage the term "BI-RADS" refers to the mammography assessment categories. These are standardized numerical codes typically assigned by a radiologist after interpreting a mammogram. This allows for concise and unambiguous understanding of patient records between multiple doctors and medical facilities.

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.

Category 6 was added in the 4th edition of the Mammography Atlas.

BI-RADS Assessment Categories are:[1]

An incomplete (BI-RADS 0) classification warrants either an effort to ascertain prior imaging for comparison or to call the patient back for additional views and/or higher quality films. A BI-RADS classification of 4 or 5 warrants biopsy to further evaluate the offending lesion.[2] Some experts believe that the single BI-RADS 4 classification does not adequately communicate the risk of cancer to doctors and recommend a subclassification scheme:[3]
