Examples of visualization of decisions made by network. A and B, 42-year-old woman (BI-RADS category 0, A) and 51-year-old woman (BI-RADS category 2, B). Both left-hand images show breast with possible suspicious findings (red arrows, A; blue arrows, B). Both right-hand images are corresponding images of same breast with regions of images (highlighted in red) that influence confidence of predictions of neural network. Dashed lines in B denote scar markers overlying left breast.
