Breast imaging-reporting and data system (BI-RADS) assessment category 0
BI-RADS 0 is one of seven categories from the breast imaging-reporting and data system and is used when imaging is incomplete such as:
- when further imaging or information is required, e.g. compression, magnification, special mammographic views, ultrasound
- when requesting previous images not available at the time of reading
In the screening setting, mammograms with suspicious findings should generally be assigned BI-RADS 0 to indicate a callback/recall for diagnostic evaluation.
In the diagnostic setting, a study should be reported as BI-RADS 0 only if there is a need for further information (e.g. focused ultrasound or outside prior exams) that is planned to be obtained at a later time.
