Normal BOLD Response to a Step CO2 Stimulus After Correction for Partial Volume Averaging

Normal BOLD Response to a Step CO2 Stimulus After Correction for Partial Volume Averaging

Cerebrovascular reactivity (CVR) is defined as the change in cerebral blood flow induced by a change in a vasoactive stimulus. CVR using BOLD MRI in combination with changes in end-tidal CO2 is a very useful method for assessing vascular performance. In recent years, this technique has benefited fro...
