Mass (a and b) and non-mass enhancement (c and d); a and b, sagittal fat-saturated T1-weighted post-contrast image of the breast (a) and subtraction image of the same slice (b) demonstrate a 1.2 cm irregular mass (arrows); c and d, sagittal post-contrast subtraction image of the breast demonstrates 1.4 cm non-mass enhancement (c, arrow). In comparison, there was no enhancement in the other breast (d).
