Reactivity of Basilar and Circle of Willis Arteries Measured Simultaneously at 7 Tesla

The subcortical conduit vessels contribute significantly to the total cerebral vascular resistance making knowledge regarding their vasoreactivity to physiological stimuli a requirement when attempting to understand regional brain perfusion. Recent evidence points to significant dilatory and constrictor potential in the middle cerebral artery. However, reactivity of the remaining conduit arteries remains poorly understood due to a need for …
