Abstract
Wallerian degeneration of the cerebral peduncle is a common MRI finding after cerebral injury. The degree of peduncular atrophy reflects the extent of damage in the corticospinal tract. The acute phase of Wallerian degeneration is visible with Diffusion-Weighted-Imaging. New investigation with Diffusion-Tensor-Imaging quantifies Wallerian degeneration in the subacute ischemic phase and is a good predictor for later functional recovery after stroke.
摘要
大脑脚的华勒氏变性是脑损伤后常见的MRI表现。大脑脚萎缩程度反映了皮质脊髓束的损伤程度。华勒氏变性的急性期在扩散加权成像上可见。扩散张量成像的新研究可量化亚急性缺血期的华勒氏变性，是中风后后期功能恢复的良好预测指标。
