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

Figure 1

(a) Diffusion weighted imaging showed an infarct in the left dorsolateral medulla on day 3 after onset; (b)–(g) diffusion tensor tractography showed axial and coronary corticospinal tract ((b)–(c) on day 3; (d)-(e) on day 14; (f)-(g) on day 30). Red for the infarct side; yellow for the contralateral side. The integrity of the corticospinal tract was preserved around the infarct.
