DWI has shown promise for detecting and characterizing breast cancers but is limited by the low spatial resolution of standard spin-echo EPI techniques. Several strategies have been proposed to generate high resolution DWI, including reduced field-of view, steady-state imaging, readout-segmented EPI, and simultaneous multi-slice imaging (SMS). In this work we adopt the Crété-Roffet blur metric to objectively compare resolution of three DWI strategies, including standard SE-EPI, and RO-segmented EPI and SMS-EPI high resolution approaches. In this comparison, both high-resolution DWI methods showed an improvement in in-plane resolution over the standard technique. The Crété-Roffet blur metric appears to be a robust and objective means of comparing effective resolution.
