Magnetic resonance imaging (MRI) of the optic nerves using the STIR (short inversion time inversion recovery) sequence was performed in 37 adult patients with a recent or past attack of optic neuritis. MRI revealed high-signal regions in 84% of symptomatic and 20% of asymptomatic nerves. The mean longitudinal extent of lesions was 1 cm. Slow or poor visual recovery was associated with more extensive lesions, or lesions within the optic canal. Disk swelling was usually associated with anterior lesions but also occurred with lesions in the canal. Visual evoked potentials were even more sensitive than MRI in detecting lesions and are still the investigation of choice in suspected demyelinating disease involving the optic nerve.
对37例近期或既往有视神经炎发作的成年患者，采用短反转时间反转恢复（STIR）序列对视神经进行了磁共振成像（MRI）检查。MRI显示，84%有症状的神经和20%无症状的神经存在高信号区。病变的平均纵向范围为1厘米。视力恢复缓慢或不佳与更广泛的病变或视神经管内的病变有关。视盘肿胀通常与前部病变有关，但也可出现在视神经管内的病变中。视觉诱发电位在检测病变方面比MRI更敏感，仍然是疑似累及视神经的脱髓鞘疾病的首选检查方法。
