MR spectroscopy methods. (A) Typical map of the distribution of NAA values (in arbitrary measurement units) at the level of the hippocampus in axial orientation. The visible grid corresponds to the acquisition matrix. A spectrum averaged over all voxels in the ROI with the integration limits for the major metabolites is also shown. (B) Corresponding contour of the employed ROI (6 MRSI voxels on each side) overlaid on this subject’s structural MRI showing location at HF. The contour of the ROI corresponds to the nominal MRSI voxel resolution.
