Abstract:Background:
CT angiography (CTA) is routinely acquired in acute ischemic stroke, providing data on extent of collaterals yet current techniques compromise either spatial or temporal resolution. We developed and validated a novel imaging technique from standard or single-phase CTA to discriminate both the spatial and temporal blood flow features in leptomeningeal collaterals.
Methods:
Consecutive acute ischemic stroke patient data, including single-phase… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
