Corticospinal Tract Change during Motor Recovery in Patients with Medulla Infarct: A Diffusion Tensor Imaging Study

Figure 3

(a) Diffusion weighted imaging showed an infarct in the left ventral medulla on day 4 after onset; (b)–(g) diffusion tensor tractography showed axial and coronary corticospinal tract ((b)-(c) on day 4; (d)-(e) on day 14; (f)-(g) on day 30). Red for the infarct side; yellow for the contralateral side. The corticospinal tract was mostly interrupted by the infarct (arrow).
