Various MR methods have been developed, in the last decade, to detect resonances of coupled spin systems which lie underneath singlets. Recently, a novel and simple approach to spectral editing has been proposed for the AB spin system of citrate: this approach exploits the signal J-modulations which occur in PRESS at a constant echo time. In the present study, we investigated with density matrix simulations and experimentally the spectral shape of glutathione at 7 Tesla, with the goal of applying this novel method of difference spectroscopy editing to the protons (ABX spin system) of the cysteine moiety of glutathione.
