Figure 4c. Mammograms obtained in the same patient as in Figure 3 14 months before detection of an ILC. In routine (a) craniocaudal and (b) mediolateral oblique views, the lesion (arrow) in the upper outer quadrant in the right breast is present but smaller than that in the later images (Fig 3a, 3b). (c) The lesion (*) is marked by the CAD system in both views. Additional marks (arrows pointing to *) on areas judged by the interpreting radiologist as not suspicious are noted in the left breast. 
= benign calcifications. (d) Digitally magnified views (craniocaudal on the left, mediolateral oblique on the right) reveal possible spiculation (arrow).
