We investigated the effect of carbogen inhalation on cerebrovascular reactivity and blood oxygenation on healthy non-human primates. We demonstrate that during the inhalation of carbogen the venous architecture slightly attenuated and then recover few minutes after pure oxygen is restore. Our data demonstrate that these SWI measurements can be used to visualize modulation of CO2 during respiratory challenge cases.
