...而是经历连锁的病理反应：首先是轴浆运输（axonal transport）在某些局部受阻，随后在阻塞处近端出现轴索肿胀（axonal swelling），继而在肿胀处出现轴索缩窄（axonal contriction），最后在受伤数小时后于缩窄断裂，这一过程称为继发性轴索断裂（secondary ax...

axonal and varicosity swelling 轴突和轴突膨体的肿胀
Diffuse axonal injury (DAI) is used to describe brain injury characterized by swelling and break of neuraxis in deep part of brain after head injury.
弥漫性轴索损伤(DAI)是用于描述头部伤后以脑深部神经轴索肿胀、断裂为特征的脑损伤类型。
Even without a positive MRI, diffuse axonal injury is not entirely excluded as the actual diagnosis is based on the pathologic finding of axonal bulbs (irregular swelling) microscopically.
即使MRI没有阳性表现，弥漫性轴索损伤也不能完全除外，实际诊断要基于镜下轴突不规则肿胀的病理学表现。
