Typical ¹H-MRS spectra obtained in the centrum semi ovale of a term neonate.

<p>The spectra were obtained from a term neonate born at 39 weeks GA and imaged at 41 weeks PCA. <b>A:</b> Localization of the voxel. <b>B and C:</b> ¹H-MRS spectra obtained at short (30 ms) and long TE (135 ms). <b>D and E:</b> Spectra processing with QUEST. A global fitted spectrum including metabolites and macromolecules was generated (“Fitted”). A second fitted spectrum corresponding to macromolecules signals only (“Macromolecules”) was produced and subtracted from the global fitted spectrum. The residue shows residual metabolites signals after subtraction of fitted metabolites and macromolecules signals. Note the absence of detectable macromolecule signals on the spectrum obtained with a TE of 135 ms. <b>Abbreviations:</b> Ala: alanine, Asp: aspartate, β-gluc: β-glucose, Glu: glutamate, Gln: glutamine, Gly: glycine, GPC: glycerophosphocholine, <i>myo</i>-Ins: <i>myo</i>-inositol, tNAA: total <i>N</i>-acetylaspartate, PC: phosphocholine, PCr: phosphocreatine, <i>scyllo</i>-Ins: <i>scyllo</i>-inositol, tau: taurine.
