Three-dimensional high-resolution diffusion imaging is feasible in terms of scan time when multislab acquisition is used. However, the main challenge of multislab acquisitions is the slab boundary artifacts caused by an imperfect slab-selective profile along the slice dimension. By reconstructing all the slab collectively using a SENSE-like method with the slab excitation profiles as the sensitivity maps, the slab boundary artifacts can be mitigated.
