The proposed SNR optimized, accelerated, phase-sensitive, dual-acquisition, single-slab, 3D, turbo/fast spin echo imaging method simultaneously enhances SNR and imaging efficiency by an optimal design of variable refocusing flip angles in the second acquisition period and elliptical incoherent sampling patterns, while simultaneously generating high resolution, isotropic, T2-weighted and CSF-suppressed images within clinically acceptable imaging time (~7mins).
