Abstract：Objective To evaluate effectiveness of the 3.0 T magnetic resonance scanner in assessment of optic nerve damage in multiple sclerosis (MS), and the relationship between clinical significance and imaging features.Methods Conventional MRI scanning of optic nerve was performed on 29 MS patients with optic nerve damage using a 3.0 T magnet system.All optic nerve images were analyzed in some aspects, including location of optic nerve damage, feature of focus, and length of optic nerve damage.MRI features of optic damage were compared with visual impairment.Results Length of optic nerve damage in poor visual acuity groups was significantly higher than in the good visual acuity groups.Incidence rate of the lesion, which was in the transverse section and the axial part of optical nerve in poor visual acuity groups, was higher than in the good visual acuity groups.Conclusion 3.0 T MRI is a effective method of diagnosis and assessment of MS optic damage, which can clearly show morphology of the optic damage and has good Correlation with visual impairment.3.0 T MRI is helpful to diagnose and assess the MS optic nerve damage.
