Note:—CTA indicates computed tomographic angiography; CTP, computed tomographic perfusion; NIHSS, National Institutes of Health Stroke Scale; RICA, right internal carotid artery; LICA, left internal carotid artery; RMCA, right middle cerebral artery; LMCA, left middle cerebral artery.
* Seen on MR angiogram.
† Seen on MR perfusion study.
‡ No perfusion imaging performed since the intervention “pre-dated routine perfusion imaging.”
