Abstract:
Objective To investigate the relationship among early parenchymal enhancement,post- gadolinium(Gd)hyperintense middle cerebral artery(HMCA),and subsequent hemorrhagic transformation (HT)in patients with hyperacute ischemic stroke.Methods Twenty-four consecutive patients with ischemic stroke who underwent MRI within 6 h[(4.3?1.4)h]of symptom onset were retrospectively reviewed.All of these patients underwent at least one follow-up MRI or non-enhanced CT study at 2 to 7 days.Post-Gd T_1WI were analyzed for parenchymal enhancement and hyperintense MCA.Gradient echo MRI and CT were used for assessment of HT.Results Ten patients developed HT on follow-up imaging (hemorrhagic group).Early parenchymal enhancement was found in 6 patients with HT(P
