Regional Differences in Cerebral Vascular Response to Paco2 Changes in Humans Measured by Positron Emission Tomography
Explore this paper's citation graph
Summary
Regional heterogeneity of the cerebral vascular response should be considered in the assessment of cerebral perfusion reserve by hypercapnia and in the correction of CBF measurements for variations in subjects' resting Paco2, indicating that cerebral vascular tone at rest might incline toward vasodilatation.
