This work investigate the correlation of DTI metrics with the clinical assessment in different WM or GM tracts. The results indicate the potential prognostic value of DTI metrics at non-compressed C2 level for degenerative cervical myelopathy.
Figure
1. Pre-
and post-surgery DTI quantitative maps of one patient with positive surgical
outcome. Slice No.2 represents a vertebral level without visible compression
while slice No.1 represents a compressed level before surgery. WM ROI (blue) and GM ROI (red-yellow) are automatically registered and labeled by SCT.

correlation
between pre-surgery (A) FA and (B) MD at C2 level and JOA recovery rate (JOA
Rec) in the following ROIs: dorsal columns (DC), lateral funiculi (LF), ventral
funiculi (VF) and gray matter (GM). The r and P values are marked
in each diagram. Correlation is considered significant if P<0.05.
