To reduce acquisition time, acceleration techniques such as simultaneous multi-slice and parallel imaging techniques have been applied to various sequences. In this work, we proposed a reconstruction method for simultaneous multi-slab spatiotemporal-encoding (SMS SPEN) using split slice-GRAPPA combined with CAIPIRINHA. The proposed method was applied to the recently developed ultrafast 3D SPEN imaging sequence called ERASE (Equal-TE Rapid Acquisition with Sequential Excitation) and a case of multiband factor of 3 was demonstrated with human brain imaging at 3T.
