Change of Neural Connectivity of the Red Nucleus in Patients with Striatocapsular Hemorrhage: A Diffusion Tensor Tractography Study

Figure 1

According to diffusion tensor tractography (DTT) findings of the corticospinal tracts (CST) based on integrity, all patients are classified according to two groups: group A, the CST in the affected hemisphere showing preservation of integrity from the cortex to the medulla, and group B, the CST in the affected hemisphere showing a discontinuation of integrity due to the lesion. (a) Brain CT images show the striatocapsular hemorrhage. (b) Results of DTT for the CST (yellow: unaffected hemisphere, red: affected hemisphere) and pathways of CST at the level of brainstem. CSTs descend the basis of pontine and terminate the pyramid of medulla. (c) Results of DTT for the neural connectivity between red nucleus and target brain regions ((A): cortex level, (B): internal capsule level, (C): upper midbrain level, (D): upper pons level, (E): lower pons level, and (F): medullar level).
