Figure 1.

(A) T2-weighted magnetic resonance images show a putaminal hemorrhage in the right hemisphere at 3 weeks and 3 months after onset. (B) Result of diffusion tensor tractography (DTT), the right corticospinal tract (CST) shows discontinuation at the brainstem on both 3-week and 3-month DTT. By contrast, on 3-month DTT, the left CST has become thinner (green arrow) compared with 3-week DTT. (C) The right corticoreticulospinal tract (CRT) shows discontinuation below the lesion on both 3-week and 3-month DTT. On 3-month DTT, the left CRT has become thicker (yellow arrow) compared with 3-week DTT.
