A novel spectral editing approach was proposed to simultaneously measure glutamate, glutamine, GABA, and glutathione at 7 T. By using a single editing pulse, a relatively short echo time of 56 ms was achieved. The main targets of the signal detection were the H2 and H4 protons of GABA and the H4 protons of glutamate, glutamine, and the glutamyl moiety of glutathione. No motion-sensitive data subtraction was required.
