Figure

Figure  1  displays  the  typical  single-voxel  spectroscopy  prescription  in  the  right  hippocampus  from  one  subject,  registered  onto  a  high-resolution  T1-  weighted  image  (Fig
Fig. 3. Boxplots for the partial volume distributions within the voxel: (a) V GM /V, (b) V WM /V, and (c) V CSF /V in each group for  left hippocampus (LH) SV, right hippocampus (RH) SV, and Posterior Cingulate (PC) SV
Fig.  4.  Mean  values  of  mI  (dark-colored)  and  NAA  (light-colored)  concentration  along  different  groups  for  (a,  d)  left  hippocampus (left column), (b, e) right hippocampus (middle column), and (c, f) posterior cingulate (right column)
Table 1 shows the results of the statistical analysis for those metabolite concentrations and ratios  which means resulted significantly differences in ANOVA, say mI, NAA, Cho, mI/Cr, and mI/NAA,  in both hippocampi and the posterior cingulate
