(b) Axial colour-coded directional image. (c) Three-dimensional tractography superimposed on an axial isotropic diffusion-weighted image (from an anteriosuperior viewpoint). (d) Three-dimensional tractography superimposed on an axial colour-coded directional image (from an anteriosuperior viewpoint). The corticospinal tract (orange lines) of the affected cerebral hemisphere appears to run through the lacunar infarct.
