Glutamate related metabolism can be measured considering the 13C labeling effects from an administered 13C labeled substrate in pure 1H MRS spectra without a 13C channel. In this work, simulated 1H MRS spectra with FID, semi-Laser, and two PRESS sequences have been compared to optimize spectral resolution for glutamate and glutamine measurements at 9.4 T. Furthermore, spectral changes according to a two-compartment model were analyzed. As a result, this work indicates the fastest possible acquisition can be obtained with an FID sequence, while the best resolution possible can be obtained with a PRESS sequence.
