Early (A) and delayed (B) contrast-enhanced subtractions, T2w (C), and ADC map (D). Mass and non-mass lesions in the left breast of a 48-year-old female undergoing MRI for staging purposes because of conventional BI-RADS 5 findings prior to biopsy. The main mass lesion shows multiple subtle spiculations, a wash-out curve type, and a perifocal oedema, corresponding to a Kaiser score of 11 (Fig. 6). Note central necrosis (high signal in C) and low ADC (0.7*10^-3 mm²/s). The anterior lesions show no spiculations, a plateau curve type, and irregular margins, corresponding to a Kaiser score of 5 (Fig. 6). Again, ADC is low (0.9-1*10^-3 mm²/s). Histopathology revealed a multicentric IDC, G3, with a DCIS component, B5b
