MR imaging in posterior circulation stroke before (a−c) and after (d−f) intravenous thrombolysis. Initial MR imaging shows the ischemic lesion on DWI (a), hypoperfusion on PWI (TTP map) (b), and vessel pathology (black arrow) on MRA (c). Follow-up MR imaging lesion on DWI (d) and T2 FLAIR imaging (e), as well as recanalization or persistent vessel pathology (black arrow) on MRA (f).
