MRI of the breast at 3.0 T: invasive lobular carcinoma grade 3 laterally in the right breast in a 44-year-old female at 3 T—the lesion (arrow) is presenting as a segmental heterogeneous non-mass enhancement [(a) pre-contrast media, (b) initial and (c) delayed enhancement] with a fast/plateau contrast enhancement (d). On diffusion-weighted imaging, there is a restricted diffusivity (e) with decreased ADC values (0.89 × 10⁻³ mm²/s) (f). On proton MR spectroscopic imaging, there is a choline peak at 3.2 ppm (dashed arrow) (g). Multiparametric MRI has accurately classified the lesion as malignant, BI-RADS 5 (highly suggestive of malignancy).
