Cervical cord lesions were most frequently located at the level of C2 (31%), C3 (15.7%) and C4 (18.1%), with a high agreement between T2/STIR and T1-MPRAGE scans (Cohen’s kappa=0.985). T1-MPRAGE scans allowed reliable lesion localization on the transverse plane, with 59% involvement of the lateral cord columns, 31% of the posterior cord, and 10% of the anterior cord.Conclusions: The combined use of sagittal T1-MPRAGE and T2/STIR improves MS cord lesion detection and localization. This might help diagnosis and ameliorate correlations with disability.Study Supported by:This study has been partially supported by a grant from Fondazione Italiana Sclerosi Multipla (FISM 2014/PMS/6).
