DWI sequences based on single-shot EPI have an
additional source of N/2 ghosting artifacts that are
associated with B0 field perturbations resulting from
diffusion gradient-induced eddy currents. Hence,
diffusion gradient-induced phase error must be
considered in DWI. In this study, we investigate the
impact of navigator echo acquisition locations. In
addition, the effect of a dummy diffusion gradient is
investigated as an alternative method reduces eddy
current.
