The major cerebral arteries proximal to the Circle of Willis contribute to cerebrovascular resistance in humans
2015
Journal of Cerebral Blood Flow and Metabolism
Cerebral autoregulation ensures constant cerebral blood flow during periods of increased blood pressure by increasing cerebrovascular resistance. However, whether this increase in resistance occurs at the level of major cerebral arteries as well as at the level of smaller pial arterioles is still unknown in humans. Here, we measure cerebral arterial compliance, a measure that is inversely related to cerebrovascular resistance, with our novel non-invasive magnetic resonance imagingbased
