Purpose: To determine which modalities [2D mammography (2D), digital breast tomosynthesis (DBT), whole breast sonography (WBS)] are optimal for screening depending on breast density.
Methods: Institutional retrospective cohort study of 2013 screening mammograms (16,789), sorted by modalities and density.
Results: Cancer detection is increased by adding WBS to 2D (P=.02) for the overall study population. Recall rate was lowest with 2D+DBT (10.2%, P<.001) and highest with 2D+DBT+WBS (23.6%, P<.001) for the overall study population as well.
Conclusion: Women with dense and nondense breasts benefit from reduced recall rate with the addition of DBT; however, this benefit is negated with the addition of WBS.
