Magnetic resonance imaging (MRI) was performed in 20 patients with multiple sclerosis and abnormal electro-oculographic examination. All but 2 patients showed MRI abnormalities in the infratentorial region: hypersignal on T2-weighted sequences and/or images of atrophy. Usually, each patient had multiple abnormalities, which could prevent anatomico-oculographic correlations. With oculomotor disorders of cerebellar origin, correlations between clinical findings and MRI images were satisfactory, but with disorders due to brainstem lesions correlations were not so good, as shown by the results in 9 patients with internuclear ophthalmoplegia.
对20例患有多发性硬化症且眼电图检查异常的患者进行了磁共振成像（MRI）检查。除2例患者外，其余所有患者均在幕下区域显示出MRI异常：T2加权序列上的高信号和/或萎缩图像。通常，每位患者都有多种异常情况，这可能会妨碍解剖学与眼电图的相关性分析。对于小脑起源的动眼神经障碍，临床发现与MRI图像之间的相关性令人满意，但对于脑干病变导致的障碍，相关性则不太理想，9例核间性眼肌麻痹患者的结果表明了这一点。
