视神经炎的磁共振成像与临床观察

Clinical follow up and magnetic resonance imaging(MRI)in optic neuritis

目的 :对 40例单一视神经炎患者进行头部磁共振 ( MRI)检查及临床观察 ,证实部分视神经炎患者存在 CNS其他部位病损。方法 :头部 MRI采用自旋回波 ( SE) ,纵向射频重复时间为 30～ 5 0 0毫秒 ,全部病人进行了 1～ 6年的随访。结果 :16例脑 MRI有异常改变 ( 40 % )。经 1～ 6年的临床随访总共有 42 .5 %的单一视神经炎发展为临床确诊的多发性硬化 ( CDMS)。结论 :视神经炎经 MRI检查有多发性硬化的可能。同时经随访部分病人发展为

Objective:To investigate CNS lesions of optic neuritis by magnetic resonance imaging.Methods:Cranial MRI were perfomed on a 0 22 Tesla magnet using spin echo technigue on 40 optic neuritis patients,thickness 5mm.During 6 years of follow up.Result:16 patients had abnormal MRI.Atotal 17 of 40 patients (42 5%)developde clinically definite multiple sclerosis(CDMS)Conclusions:We found higher develop frequence from optic neuritis to MS and optic neurintis is one of the commonest isolated manifestation form of MS.
