Echo-Planar-Imaging (EPI) is often used in DW-MRI to acquire a full volume in a short period of time. These images, however, show substantial local geometric and intensity distortions due to the susceptibility artefact. A popular method to correct for these distortions is to acquire a pair of images with opposite phase-encoding-directions (PED) but same slice-encoding-direction (SED) from which the distortion field can be estimated. While the choice of SED and PED likely impacts the correction effectiveness, it has never been rigorously quantitatively evaluated. In this work, we acquired scans with all combinations of SEDs and PEDs and evaluated the correction quality of three different distortion correction implementations.
