Purpose-To investigate the visibility of mammographically occult breast cancers on diffusionweighted MRI (DWI) versus ultrasound. (n=60) initially detected on contrast-enhanced MRI that underwent pre-biopsy targeted ultrasound were retrospectively evaluated for visibility on DWI and ultrasound.. Materials and Methods-Mammographically occult breast cancers Results-More cancers were visible on DWI than ultrasound (78% vs. 63%; p=0.049), with 32 (53%) visible on both and 7 (12%) not visible on
