  4. Example In the right breast, an approximately 1.0 cm mass is identified in the right upper inner breast. This mass is noncalcified and partially obscured and lobulated in appearance.

  5. Materials & Methods • Training on 146,972 mammograms • Testing on same academic institution as training and on different private institution • Replicate algorithm into Portuguese language, and test on Portuguese set • All test sets manually annotated

  6. Results

  7. Conclusion • Automated BI-RADS extractor: • Performs no worse than manual extraction • Generalizes across institutions • Generalizes across languages • Enables the incorporation of free-text data into breast cancer risk prediction tools
