Fig 2. Representative data from a 1H-MR spectroscopy study on a nonhuman primate at both 3 days (A, -B) and 10 days (C, -D) following a small left hemispheric stroke (infarct volume, 28% of hemisphere). A and C, T2-weighted MR images are used to prescribe the spectral sections at (A) day 3 and (C) day 10. B and D, 1H-MR spectroscopy voxel grid and corresponding normalized spectra (FOV, 200 mm; thickness, 15 mm; each voxel was a volume of 15 x 12.5 x 12.5 mm per side with a capacity of 2.34 mL) are overlaid on magnified views of the T2-weighted MR images from (B) day 3 and (D) day 10. The voxel grids are labeled horizontally with numbers (1-4) and vertically with letters (a–d) to allow direct comparison between spectra collected at 3 and 10 days.
