Fig. 8:

A mammographically occult example with a biopsy-proven malignant finding. From left to right: the original image, the saliency map for benign findings, the saliency map for malignant findings, and the sagittal ultrasound image of this patient. While the asymmetry in the left lateral breast posterior depth was intepreted as benign by the radiologist, a subsequent screening ultrasound and ultrasound-guided biopsy yielded mammographically-occult moderate grade invasive ductal carcinoma. On saliency maps, this area shows a weak probability of benignity and a high probability of malignancy.
