Fig. 3. Results of metabolites with MRS. T2WI showed the location of MRS voxel (white squre, 3×3×3 µL) in the peri-lesional site (A). There are no significant differences in Cho/Cr (B) or NAA/Cr (C) ratios between the two groups (sham, n=10 rats; rTMS, n=10 rats). Cho, choline; Cr, creatine; NAA, N-acetyl-aspartate; D4, 4 days after injury; D18, 18 days after injury; D25, 25 days after injury.
