The scanning protocol included scouting of standard view using SPGR sequence, FRFSE T2WI sequences on standard sagittal and axial views ,T1FLAIR sequence on sagittal view,and SE-EPI sequence on sagittal view for DTI.

• 检查程序包括使用SPGR序列进行颈髓的定位扫描，使用FRFSE序列完成矢状面及横轴面T2加权像扫描，使用T1FLAIR序列完成矢状面T1加权像扫描，使用SE-EPI序列完成扩散张量成像扫描。
