A T1-WI: showing an ill-defined area of the intermediate signal intensity at the LOQ. B T2-WI: a non -circumscribed mass of irregular shape and margin is seen at the previously described area on T1WI at the lower inner quadrant of the right breast. It exhibits intermediate high SI. C, D Dynamic and subtraction images: The irregular shape and margin of the previously described mass are now more evident. The mass shows a heterogeneous enhancement pattern. E TIC: exhibiting type II (plateau enhancement) curve. F DWI at b = 1000: the lesion shows high signal intensity. G Axial grayscale ADC map: showing the lesion with restricted diffusion and calculated mean ADC value = 0.6 X10 − 3 mm2 /s. Final molecular diagnosis: Luminal A breast cancer. BIRADS (MRI-Lexicon):4, BIRADS (Kaiser Score): 4
