For PRESS spectroscopy of glutamate in the human brain, the choice of field strength can play a large role in affecting the optimal timings and yields, however, the voxel location (occipital lobe, frontal lobe or midbrain) is also critical to consider since susceptibility effects from tissue-air and tissue-iron interfaces play an increasing role with increasing field. We assess these effects for a range of field strengths.
