DBT know-how boosts FFDM recall, cancer detection rates
March 15, 2018 -- A study in the March issue of Radiology indicates that experience with digital breast tomosynthesis (DBT) may change the way breast imagers interpret 2D mammograms in subtle but significant ways. Researchers found higher recall rates in this scenario, but also a boost in cancer detection rates and positive predictive value.  Discuss
