Figure 2.
Axial DTI images obtained from ex vivo rat spinal cord specimens at the injury site (thoracic cord), and at a rostral site in the cervical spinal cord, 10 weeks after contusive SCI of varying severity. Fractional anisotropy (FA) maps demonstrate loss of anisotropy at the injury site. Sham spinal cords showed intact cord structure with normal central gray matter morphology. Bar graph showing significant differences between severity groups in mean diffusivity of the cervical spinal cord sections. * P<0.05
