Artifacts on DBT. The two-dimensional DM CC view (A) from a screening mammogram of a woman with an almost entirely fatty breast demonstrates “eggshell” calcifications caused by benign oil cysts. A single reconstructed slice from the CC DBT imaging (B) shows a few calcifications in focus but others are out of focus because of their out-of-plane position, above and below the reconstructed plane viewed. One can imagine that such artifacts created by the reconstruction of out-of-plane coarse calcifications or clips from biopsy could obscure the detection of clinically significant findings.
