The cerebral hemodynamics of patients undergoing revascularization surgery for intracranial steno-occlusive disease (IC-SOD) were assessed by deriving an estimate of their cerebrovascular resistance response to CO2 from their BOLD response to CO2. Significant improvements were found in the sigmoid parameters describing their resistance responses.
