Figure 1c. Current screening mammogram obtained in a 72-year-old woman. The radiopaque circle in the upper inner quadrant of the left breast is a skin marker. (a) Craniocaudal and (b) mediolateral oblique views of an asymmetric density (arrow) in the upper outer quadrant of the right breast. (c) Low-resolution digitized images of both breasts with CAD markers (*). The CAD system detects the spiculated mass (ILC) in both views. An additional mark (arrow) is present in the subareolar left breast in the mediolateral oblique view only. This area was classified by the interpreting radiologist as superimposed breast tissue. (d) Digitally magnified images (craniocaudal on the left, mediolateral oblique on the right) demonstrate a 1.5-cm irregular mass (arrows) with spiculation, best seen in the mediolateral oblique view.
