Diffusion Tensor Imaging Evaluation of Corticospinal Tract Hyperintensity in Upper Motor Neuron-Predominant ALS Patients
Figure 2
Fractional anisotropy (FA) at four CST levels on left (a) and right (b), revealing significantly lower values in right MC and left IC of CST hyperintense and CST nonhyperintense patients compared to controls. . Key: CP, cerebral peduncle; IC, posterior limb of internal capsule, LV, centrum semiovale at top of lateral ventricle, MC, subcortical to motor cortex.
