Abstract
Long-repetition-time spin-echo MR images showed symmetric hyperintensity of the intracerebral corticospinal tracts in two patients with clinical and neurophysiologic diagnosis of primary lateral sclerosis and amyotrophic lateral sclerosis. In both, axial low-flip-angle gradient-echo images of the cervical spine showed hyperintensity of the lateral columns of the cord consistent with antegrade degeneration of the crossed corticospinal tracts.
摘要
长重复时间自旋回波磁共振成像显示，两名经临床和神经生理学诊断为原发性侧索硬化症和肌萎缩侧索硬化症的患者，其大脑皮质脊髓束出现对称性高信号。在这两名患者中，颈椎的轴向低翻转角梯度回波图像均显示脊髓侧柱高信号，与交叉皮质脊髓束的顺行性退变一致。
