| Zusammenfassung | Successful implementation of MB WURST pulse for simultaneous two-voxel applications • Symmetrical regions, e.g., the motor cortices, exhibit very small differences in concentrations, CRLBs, linewidths and SNRs between individually and combinedoptimized B0 shim and B1+ settings • Regions that are more distant and in differing surrounding tissue exhibit decreased spectral quality, SNR, and linewidth for combined-optimized settings → Possible limitation for multi-voxel applications → Well suited for multi-voxel applications → Well suited for multi-voxel applications • No minimal distance limitation despite unintended partial inversion |
