Different diffusion weighted sequences, including 2D
DW-EPI, 2D simultaneous multi-slice EPI, 3D multi-slab
EPI and an parameter optimized 3D DW-SSFP, were
theoretically compared in terms of relative SNR and SNR
efficiency concerning a complete brain scan. Therefore,
an optimization of 3D DW-SSFP parameters was performed
using an analytic model provided by Freed et al.. The
analysis depicts 3D multi-slab EPI as the method of
choice for highly efficient neuro-imaging at higher
resolutions.
