Tmax: time-to-maximum of residue function; Vol_Tmaxa–b: tissue volume as indicated by Tmax a–b s; rCBV_Tmaxa–b: mean relative CBV of the brain tissue as indicated by Tmax a–b s. ^a Significantly different between groups defined by CTA collateral score (p < 0.05). ^b Significantly different between groups defined by mRS (p < 0.05).
