abstract：BACKGROUND AND PURPOSE:We hypothesize that reversal in diffusion-weighted imaging (DWI) volume at 24 hours predicts favorable clinical outcome only if accompanied by immediate reperfusion. Our aim was to quantify the immediate DWI and mean transit time changes at 2 and 24 hours after intravenous tissue-type plasminogen...
