Under a static shim setting, multi-voxel in-vivo spectroscopy requires that voxels be in close vicinity of one another such that a single static shim setting is sufficient for all voxels. Without sufficient homogeneity in all voxels, spectral resolution quickly degrades and water suppression deteriorates. Utilizing a custom-built pre-emphasized dynamic shim updating (DSU) system, we have performed rapid interleaved multi-voxel spectroscopy for voxels in widely different regions of the human brain.
