Quantification of venous vessel size in human brain in response to hypercapnia and hyperoxia using magnetic resonance imaging

Hypercapnia and hyperoxia give rise to vasodilation and vasoconstriction, respectively. This study investigates the influence of hypercapnia and hyperoxia on venous vessel size in the human brain. Venous vessel radii were measured in response to hypercapnia and hyperoxia. The venous vessel radii wer...
