From the Pioneer study using the Seno Imagio linear system: example of downgrading BI-RADS 4A to 3. Images in a 25-year-old woman: (A) internal US image showing mass assessed as a BI-RADS 4A with recommendation for biopsy. (B) PA/US combined map with no internal and external OA features, resulting in a low OA score and a downgrade to BI-RADS 3. Biopsy revealed benign fibrocystic changes.
