Cerebrovascular autoregulation ensures adequate blood perfusion to match demands for oxygen and nutrients. Cerebrovascular reserve (CVR) is defined as the maximal capacity under a vasodilatory challenge. The present work used MRI to measure CVR in rhesus brains, in order to evaluate its responsiveness and test-retest repeatability in readiness for possible use in clinical trials.
