Abstract

We evaluated the ability of MRI using short T1 inversion recovery (STIR) to diagnose optic neuritis. Eleven patients with previous or recent attack of optic neuritis were studied with MRI at 0.5 tesla. STIR images revealed high signal regions in 7 of 12 symptomatic and 5 of 10 asymptomatic nerves. Three of five asymptomatic nerves with high intensity were pertinent to the cases with past attack and seemed to reflect the demyelinating change. The other two nerves were pertinent to the cases without past attack and seemed to show occult lesions. We consider that STIR is useful in detection of optic nerve lesions associated with optic neuritis.

摘要

我们评估了使用短T1反转恢复序列（STIR）的MRI诊断视神经炎的能力。对11例既往或近期患有视神经炎发作的患者进行了0.5特斯拉的MRI研究。STIR图像显示，12条有症状神经中的7条以及10条无症状神经中的5条出现高信号区域。5条高强度无症状神经中的3条与既往发作病例相关，似乎反映了脱髓鞘改变。另外两条神经与无既往发作病例相关，似乎显示出隐匿性病变。我们认为STIR有助于检测与视神经炎相关的视神经病变。
