BI-RADS 5th Edition Quantra density categories (QDC). Evaluation of breast density categories performed by the Quantra softare (version 2.2.3) on digital breast tomosynthesis images according to BI-RADS 5th Edition. The lower boxes report the results of the Quantra evaluation for each breast and the final breast density assigned based on the denser breast. In these cases, since left and right breasts received the same evaluation, we showed only the left breast in medio-lateral-oblique (MLO) projection. Category A: almost entirely fat; category B: scattered fibroglandular densities; category C: heterogeneously dense; and category D: extremely dense.
