Benign mass detected in a 45-year-old patient undergoing MRI for high risk screening. a DCE post-contrast image demonstrates an 18-mm irregular mass with irregular margins in the left breast 7 o’clock (arrow), assigned a BI-RADS category 4. DTI-derived parametric maps of b apparent diffusion coefficient (ADC), c fractional anisotropy, and eigenvalues d λ1, e λ2, and f λ3 are shown for the lesion regions overlaid in color on the b = 800 s/mm2 image. ADC, λ1, λ2, and λ3 are in units of 10−3 (mm2/s). The mass demonstrated high ADC (mean ADC = 2.00 × 10−3 mm2/s) and very low FA (FA = 0.10), with λ1 = 2.20 × 10−3 mm2/s, λ2 = 2.00 × 10−3 mm2/s, and λ3 = 1.80 × 10−3 mm2/s. Ultrasound-guided biopsy revealed benign fibroadenoma
