Statistics with p-values\<0.05 were reported as significant. RESULTS: We detected: smaller CCA in NMOSD than HCs (mean=75.6 mm{\texttwosuperior}[{\textpm}11.4] vs. 85.8[{\textpm}11.4]) and in MS than HCs (76.5mm{\texttwosuperior}[{\textpm}11] vs. 85.8[{\textpm}11.4]), with no significant difference between patient groups; CCA reduced with longer disease-duration (r=-0.58) in NMOSD, and with worse disability (9-HPT test r=-0.51, handgrip-strength r=0.47) in MS. Compared to HCs, NMOSD patients showed reduced FA in GM and posterior-WM; higher RD in posterior-WM and AD in lateral-WM. MS patients had lower FA in the lateral-WM than HC. No difference in diffusion measures between patient groups was seen. In NMOSD, FA and RD of the posterior-WM were associated with worse vibration-perception (r=-0.63 and 0.52, respectively). CONCLUSION: Pathological involvement of spinal cord, as reflected by DTI, does not differ between NMOSD and MS. In NMOSD patients diffusion abnormalities in the posterior-WM may contribute to physical disability.Disclosure: Dr. Cortese has nothing to disclose. Dr. Magnollay has nothing to disclose.
