From: The value of MRI for downgrading of breast suspicious lesions detected on ultrasound
True-negative case of MRI finding for a lesion with US BI-RADS 4A category. a Gray-scale US revealed 29 mm non-mass hypoechoic area on the right breast and 4A category was given. b, c Dynamic contrast-enhanced MRI showed an irregular mass with circumscribed margin and persistent kinetics. d The lesion showed slight hyperintensity on DWI, with mean ADC values of 1.51 × 10–3 mm2/s. BI-RADS 3 category was given on MRI. Pathology revealed fibrocystic changes
