Abstract: Digital breast tomosynthesis (DBT) screening outcomes are sustainable over consecutive years with significant reductions in recall and increasing cancers per recalled patients compared to screening with digital mammography alone (DM). There is a prevalence effect with a reduction in cancer detection at the second round of screening that is no longer present at the third round. There is a non-statistically significant trend of decreased interval cancers with DBT compared to DM alone screening. Early data on the implementation of synthetic 2D (s2D) imaging coupled with DBT shows maintenance of screening outcomes with reduction in radiation dose compared to DM/DBT screening .
