Diffusion weighted MRI demonstrates abnormal pyramidal tract in hemiparesis
Statistics from Altmetric.com
Diffusion weighted imaging (DWI) is a magnetic resonance imaging technique which is sensitive to the molecular motion of water and allows measurements of anisotropy (the directionality) of water diffusion.1 Measurements of anisotropy provides information about tracts, because water molecules travel predominantly parallel but not perpendicular to tracts.2 The anisotropy of diffusion can be …
