Mammogram (2 of 3) (IMAGE) Radiological Society of North America Caption Images show example of a screening-detected lesion in a 67-year-old breast cancer screening patient. (a) Diffusion-weighted imaging with background suppression (b = 1500 sec/mm2 ) maximum intensity projection (MIP), displayed with black-white inversion, clear depicts the focal lesion as an area of focal diffusion restriction. (b) First postcontrast subtraction MIP shows an area of subtle enhancement that is partially obscured by generally increased background enhancement.
