What steps follow a BI-RADS 0 assessment?

• A. Obtain additional imaging (additional views or ultrasound) to reach a definitive assessment; after additional imaging, assign BI-RADS category 0–6 and determine the need for biopsy or follow-up.
• B. Immediately biopsy.
• C. Conclude screening is normal.
• D. Schedule MRI only.

Answer: (A)

BI-RADS 0 means the current study is incomplete and cannot yield a final assessment. The main idea is to obtain more information so you can reach a definitive category. The next step is to acquire additional imaging—such as extra mammographic views or a targeted ultrasound—and review any available prior studies. After this additional imaging is performed and findings are evaluated, you then assign a final BI-RADS category (ranging typically from 0 to 6) and decide whether a biopsy is indicated or whether surveillance/follow-up is appropriate.

So, the correct choice reflects the necessary workflow: pursue further imaging to complete the assessment, then finalize the BI-RADS category and determine the need for biopsy or follow-up. Immediate biopsy would be premature without more information, concluding the screening as normal would ignore the incomplete status, and scheduling MRI only is not the required first step for completing a BI-RADS 0 assessment.
