Fig 3. Mean diffusion measurements across lesions for all subjects with chronic SCI. A–C, Longitudinal diffusivity (l) (A), transverse diffusivity (t) (B), and mean diffusivity (MD) (C) are shown as a function of distance (in millimeters) from the location of ASIA neurologic impairment. D, FA across the lesion is shown as a function of vertebral level. The black line represents clinically complete SCI, and gray lines represent clinically incomplete SCI. Dashed lines represent mean control data. Data shown represent mean values ± SEM across SCI subjects (complete, n = 4; incomplete, n = 5).
