MR images of a 73-year-old-woman with invasive ductal carcinoma. a Axial fat-suppressed dynamic contrast-enhanced T1-weighted image depicts a 19 mm-sized irregularly shaped, irregularly marginated, heterogeneous enhancing mass at right middle-inner breast. b and c In the same image, the computer-aided detection system displayed the mass as the presence of color overlay that measured 17 mm at the 30% threshold and 9 mm at the 50% threshold. d The enhancing mass was not detected at the 100% threshold. e Actual pathologic tumor size was 22 mm on gross specimen
