Cohen EO, et al. - A retrospective review was performed to compare outcomes of findings seen on one view only from screening full-field digital mammography (FFDM) and FFDM plus digital breast tomosynthesis (DBT). From February 2011 through June 2014, 103,070 consecutive screening mammograms obtained at two community-based breast centers were involved. Pearson chi-square test and Fisher exact test were performed in this investigation. Results of this study suggested that one-view-only findings occur with both FFDM and FFDM-DBT and remain an important but uncommon sign of malignancy. One-view-only findings were more frequent, were more likely to represent summation artifacts and had a lower positive predictive value with FFDM than with FFDM-DBT.
