摘要

弥散张量成像可表征水分子扩散过程的取向特性，能有效观察和追踪脑白质纤维束。脑卒中患者各向异性分数下降表明纤维结构完整性受损，显著下降提示可能出现华勒变性；各向异性分数升高与运动功能恢复程度有关；患健侧各向异性分数比更适合成为脑卒中患者运动功能恢复预测指标。纤维束成像显示的皮质脊髓束变化，也可作为脑卒中患者运动功能结局的预测指标。

Abstract

Diffusion tensor imaging (DTI) can be used to characterize the orientation of water diffusion, and track white matter fiber bundles. The decrease of fractional anisotropy after stroke indicates impairment of structural integrity of fibers, even Wallerian degeneration if serious; in another hand, the increase of fractional anisotropy relates to the more recovery of motor function. The affected/unaffected ratios of fractional anisotropy are more suitable for predicting motor function recovery after stroke. The changes of corticospinal tract in diffusion tensor tractography can also predict the motor outcome in stroke patients.

Key words： stroke; diffusion tensor imaging; motor function; prognosis; review
