Early (A) and delayed (B) contrast-enhanced subtractions, T2w (C), and ADC map (D). Mass lesion in the left breast of a 50-year-old female with several unclear mass lesions in both breasts; MRI obtained for treatment planning. The lesion shows no spiculations, a wash-out enhancement curve type, and a heterogeneous internal enhancement, corresponding to a Kaiser score of 8 (Fig. 6). Note high signal intensity on T2w. Due to high ADC (1.9*10-3 mm2/s), the lesion was downgraded to a Kaiser score of 4. Histopathology revealed a fibroadenoma with regressive changes, B2
