The
purpose of this study was to evaluate the cerebral blood change in one cardiac
cycle in different concentration of carbon dioxide inhalation. Using
retrospectively gated 2D phase contrast MRI is suitable method for measuring
the velocity of cerebral arteries and veins during one hear beat. It is
noninvasive modality to quantify the blood flow and blood volume in one heart
cycle with high spatial and temporal resolution. By this MR method, we
proceeded the experiment that observe the blood flow change during the CO2
concentration change.
