Figure 4. Baseline CBF and diffusion tensor imaging variables of the new deep WMH and persistent NAWM voxels of the inner 5 NAWM penumbra layers.

(A) cerebral blood flow (CBF), (B) fractional anisotropy (FA), (C) mean diffusivity (MD), (D) axial diffusivity (AD), and (E) radial diffusivity (RD). NAWM = normal-appearing white matter; WMH = white matter hyperintensity.
