AI DBT Impact on Mammography Post-breast Therapy

AI-CAD marked axillary lymph node and region in right upper outer quadrant (arrows and thin line outlining both sites) and assigned an abnormality score of 28%. August 11, 2021 -- According to an open-access Editor's Choice article in the American Journal of Roentgenology (AJR), artificial intelligence-based computer-aided detection (AI-CAD) can be a practical addition for lowering false-positive findings when performing post-breast conserving therapy (BCT) surveillance mammography. "After BCT, adjunct digital breast tomosynthesis (DBT) or AI-CAD reduced recall rates and improved accuracy in the ipsilateral and contralateral breasts compared with digital mammography (DM)," wrote lead investigator Jung Hyun Yoon. "In the ipsilateral breast, addition of AI-CAD resulted in lower recall rate and higher accuracy than addition of DBT." Yoon and colleagues' single-center retrospective study included 314 women (mean age, 53.2 years; 4 with bilateral breast cancer) who underwent BCT followed by DBT (mean interval from surgery to DBT, 15.2 months). Three breast radiologists independently reviewed images in three sessions: DM, DM with DBT, and DM with AI-CAD.
