^*DTI metrics were defined as rX = (X_ipsilateral − X_{contralateral}) / X_{contralateral}, where X indicates value of indices (mean ± standard error of the mean). DTI = diffusion tensor imaging, IC = infarct core, NT = normal tissue, rAD = relative axial diffusivity, rFA = relative fractional anisotropy, rL = relative diffusion magnitude, rMD = relative mean diffusivity, rq = relative pure anisotropy, rRD = relative radial diffusivity, TP = true penumbra
