Representation of DTI processing of the ROIs.

(A–C) DTI processing was performed with the commercially available software Neuro3D (Siemens NUMARIS/4, Syngo MR D13) embedded in a Siemens post-processing workstation. Based on the T1-weighted images, the circular ROIs (5 mm²) were placed at CP (A), PLIC (B), POG and PRG (C), and the corresponding FA and ADC values were then measured. The ROIs were placed bilaterally on three slices that covered each of the selected structures. The final values were calculated using the average of the three slices. Control group: n = 5; SCI group: n = 10. ADC: Apparent diffusion coefficient; CP: cerebral peduncle; DTI: diffusion tensor imaging; FA: fractional anisotropy; PLIC: posterior limb of internal capsule; POG: postcentral gyrus; PRG: precentral gyrus; ROI: region of interest.
