The detection of weak neurometabolites such as g-aminobutyric acid (GABA), glutathione (GSH), glycerophosphocholine (GPC), phosphorylethanolamine (PE) with 2D L-COSY can be challenging due to lower concentrations. Moreover, the standard initial echo time (TEinitial) of 30ms yields suboptimal SNR due to shorter T2*. In this study, we compared short TEinitial of 20ms vs 30ms to evaluate improved detection of low concentration metabolites. Our results show a significant increase in SNR with TEinitial of 20ms compared to 30ms. Short TEinitial of 20ms has increased potential in the detection of peaks from weak neurometabolites.
