Diffusion Tensor Imaging Evaluation of Corticospinal Tract Hyperintensity in Upper Motor Neuron-Predominant ALS Patients
Figure 4
Axial diffusivity (AD) at four CST levels on left (a) and right (b), revealing significantly lower values at the IC level bilaterally in only CST hyperintense 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.
