Diffusion Tensor Imaging Evaluation of Corticospinal Tract Hyperintensity in Upper Motor Neuron-Predominant ALS Patients
Figure 6
Sagittal views of FA color maps showing tractography-derived CST extending up to the submotor cortex (SMC) level in a control subject (a) but truncated in an UMN-predominant ALS patient with CST hyperintensity (b).
