Female patient aged 35 years old presented by palpable left breast mass. A axial early subtraction MRI image shows Irregular shape, heterogeneously enhanced soft tissue mass with speculated margin within the upper inner quadrant of the left breast, B, C axial DWI and ADC show high signal intensity within DWI and low signal intensity in ADC map (restricted diffusion) with mean ADC value = 0.9 × 10–3 mm2/s. D axial DTI image shows FA value = 0.5. E, F Time Intensity curve shows Type II curve (plateau curve) with maximum enhancement about 1636, time to peak 426 s without washout. G Pathological diagnosis was grade II invasive ductal carcinoma, luminal A (ER and PR positive and low Ki-67 index (ki-67 = 5%)
