Internal carotid artery stenosis associated with giant cell arteritis: case report and discussion.
Cerebrovascular ischemic events associated with giant cell arteritis (GCA) are uncommon and have been reported in 3%-4% of patients. We describe a case report of GCA associated with intracranial stenosis and review various angiographic findings. ⋯ Bilateral internal carotid arteries stenosis may be seen in patients presenting with typical symptoms of GCA and may persist after steroid treatment despite resolution of clinical symptoms.

Mean transit time on Aquilion ONE and its utilization in patients undergoing acute stroke intervention.
Neuroimaging techniques have been beneficial in identifying patients with salvageable penumbra. We sought to validate the mean transit time (MTT) map on computed tomography perfusion (CTP) imaging utilizing an Aquilion ONE computed tomography (CT) scanner running a singular value decomposition plus algorithm in patients with acute large vessel ischemic stroke who underwent endovascular therapy. ⋯ Although further studies are required to validate this retrospective study, preliminary data suggest that cMTT maps can be a valuable and accurate tool in the assessment of patients with acute stroke who may benefit from aggressive endovascular therapy.
