Objective: to discuss the causes of symmetric lesions of subcortical gray matter nuclei with clinical manifestation from neuroimaging study, and to improve the diagnosis ability.
结果：灰质核团t2弛豫时间随脑铁含量增加而缩短，脑白质t 2弛豫时间无变化趋势。
Results: T2 relaxation time of gray matter nucleus was shorten because of iron content increasing, and that of white matter had not this change.
