Multi-echo Turbo Spin Echo reconstruction with six echoes and Simultaneous MultiSlice acceleration (displaying 5 out of 10 slices). Root-sum-of-squares combination of the echoes using MultiBand=10 acceleration are depicted. Conventional Slice GRAPPA with signal leakage constrained yielded 5.1% error and structured aliasing artifacts (yellow arrows). JVC Slice GRAPPA obtained a reduced RMSE of 3.6% with better noise suppression and artifact mitigation. However, some aliasing artifacts were still visible. Joint SMS LORAKS provided the lowest error 3.3% with better artifact suppression.
