Accurate measurement of in vivo relaxation times is necessary for quantitative in vivo magnetic resonance spectroscopy. Recent work applying edited MRS of GABA has generally quoted concentrations in institutional units or as signal ratios, in part because the in vivo relaxation times of GABA are unknown. In this abstract, we characterize the TE-dependence of edited GABA detection at 7T and show that this knowledge allows T2 to be measured (T2 = 53 ms).
