Changes in Biopsy Recommendations (Change in BI-RADS categories from DBT to DBT/3D-AUS)
| Malignant Masses | Benign masses | Cysts | ||||
|---|---|---|---|---|---|---|
| Radiologist No. | Beneficial | Detrimental | Beneficial | Detrimental | Beneficial | Detrimental |
| 1 | 1 | 0 | 4 | 7 | 2 | 1 |
| 2 | 1 | 0 | 3 | 17 | 3 | 5 |
| 3 | 0 | 0 | 7 | 12 | 6 | 4 |
| 4 | 1 | 0 | 4 | 8 | 2 | 3 |
| 5 | 0 | 0 | 4 | 0 | 4 | 0 |
| 6 | 0 | 0 | 5 | 1 | 4 | 0 |

Note: Change in BI-RADS categories denotes a change from category 1, 2 or 3 (“no biopsy”) to category 4, or 5 (“biopsy recommended”). A beneficial change for a malignant mass is a decision based on DBT/3D-AUS to recommend biopsy for the mass that was not recommended for biopsy based on DBT alone. A beneficial change for a benign mass (including the cysts) is a decision based on DBT/3D-AUS not to recommend biopsy for the mass that was recommended for biopsy based on DBT alone.
