目的检验-假说,即视神经脊髓炎的白质损害比先前描述的更广泛,其很可能包括表现正常的白质。应用扩散张量(DT)成像技术探究白质损害是否不仅与华勒氏变性有关,而且也可由脱髓鞘造成。材料与方法17例视神经脊髓炎病人(平均年龄45岁,14例为女性)与17名性别和年龄 The purpose of the test - the hypothesis that optic neuromyelitis white matter damage is more extensive than previously described, it is likely to include normal white matter. Diffusion tensor imaging (DT) imaging is used to investigate whether white matter damage is not only linked to Werner’s degeneration but also to demyelination. Materials and Methods 17 cases of optic neuromyelitis patients (mean age 45 years, 14 females) and 17 gender and age
