Abstract
Three of 7 patients with amyotrophic lateral sclerosis had bilateral signal loss confined to the motor cortex on T2-weighted magnetic resonance images. None of the control subjects had this abnormality. Although not present in every patient, this finding might reflect the primary pathological process of the motor cortex in amyotrophic lateral sclerosis.
摘要
7例肌萎缩侧索硬化患者中有3例在T2加权磁共振图像上出现双侧信号缺失，且仅限于运动皮层。对照组中无一例有此异常。虽然并非每个患者都有此表现，但这一发现可能反映了肌萎缩侧索硬化中运动皮层的主要病理过程。
