Abstract:
Objective Investigate MR resonance diffusion tensor im-aging (DTI) characteristics of non-pyramid tracts in the patients with amyotrophic lateral sclerosis(ALS). Methods 21 patients with ALS were served as case group.20 healthy volunteers were served as healthy controls. All subjects underwent a DTI sequence, chose region of interest (ROI) to measure fractional anisotropy (FA) and mean diffusivity (MD).Results In case group, FA decreased on the splenium of corpus callosum (0.73?0.087)(u=-2.004,P
