MRI of the breast at 3.0 T: invasive ductal carcinoma in the right breast in a 60-year-old female—the extensive lesion occupying almost the whole right breast is demonstrating an irregular shape and margins [(a) pre-contrast media, (b) initial and (c) delayed enhancement], fast/washout enhancement (e), a restricted diffusivity (f) and decreased apparent diffusion coefficient (ADC) values (881 × 10−3 mm2/s) (g). In baseline MRI before neoadjuvant cytotoxic chemotherapy, an additional enhancing lesion has been detected in the left breast lateral. The 7-mm non-mass enhancement (arrows) is demonstrating an irregular shape and margins [(a) pre-contrast media, (b) initial and (c) delayed enhancement], fast/plateau enhancement (d), restricted diffusivity (f) and decreased ADC values (1004 × 10−3 mm2/s) (g) and has been confirmed to be high-grade ductal carcinoma in situ.
