Fig. 1. Maps of DTI metrics measured at 30 minutes post pMCAO.

Note relative hypointensity changes within hemisphere ipsilateral to pMCAO on maps of q (B), L (C), MD (D), AD (E), and RD (F), with exception of FA (A) which shows symmetrical signal intensity. AD = axial diffusivity, DTI = diffusion tensor imaging, FA = fractional anisotropy, L = diffusion magnitude, MD = mean diffusivity, pMCAO = permanent middle cerebral artery occlusion, q = pure anisotropy, RD = radial diffusivity
