This study presents a novel implementation of established methods to eliminate ghosting artifacts in Multi Dimensional diffusion MRI (MD-dMRI) images. By replacing scan time used for acquiring images purely used for averaging (when applicable), with EPI acquisitions at opposing readout directions, ghost artifacts can be eliminated. The implementation provides ghost-free images with a small increase in SNR and a minimal (7%) increase in scan time.
