The brain's collateral circulation consists of arterial anastomotic channels capable of
providing nutrient perfusion to brain regions whose normal sources of flow have become …

Stroke is a leading cause of long-term disability, and outcome is directly related to timely
intervention. Not all patients benefit from rapid intervention, however. Thus a significant …

Background Trials of endovascular therapy for ischemic stroke have produced variable
results. We conducted this study to test whether more advanced imaging selection, recently …

Background Despite significant advancements in the procedural efficacy of mechanical
thrombectomy in patients with ischemic stroke in recent years, there still remains a portion of …

Background and Purpose—Computed tomographic perfusion represents an interesting
physiological imaging modality to select patients for reperfusion therapy in acute ischemic …

Background Endovascular or intra-arterial treatment (IAT) increases the likelihood of
recanalization in patients with acute ischemic stroke caused by a proximal intracranial …

Purpose To validate the use of perfusion computed tomography (CT) with whole-brain
coverage to measure the ischemic penumbra and core and to compare its performance to …

Background Treatment strategy for acute arterial occlusions due to intracranial
atherosclerotic disease (IAD) may differ from those due to embolism (embolic). The aims …

Background: Determining the size of infarct extent is crucial to elect patients for reperfusion
therapies. Computed tomography perfusion (CTP) based on cerebral blood volume may …

Purpose Stent retriever-based mechanical thrombectomy (MT) for emergent large vessel
occlusions (ELVO) is often complicated by thrombus fragmentation causing distal …
