We develop flip-angle single-slab 3D GRASE imaging, incorporating multiple echo planar imaging (EPI) readouts into a framework of turbo/fast SE imaging, to enhance the imaging efficiency without the direct trade off with SNR. To avoid the phase discontinuity induced problems, phase-independent image reconstruction is performed, in which each echo k-space is regenerated by GRAPPA-like parallel imaging technique employing within-and between- group k-space correlations and then averaged to retain SNR efficiency.
