Abstract
In patients with cerebrovascular disease the acetazolamide (ACZ) test is performed to evaluate the decrease in cerebral perfusion pressure through the investigation of the vasomotor reactivity (VMR). The latter is currently assessed with ACZ using several methods. Dynamic susceptibility contrast-enhanced gradient echo MRI techniques (DSC-MRI) might be an attractive tool to assess VMR. We described the course of VMR in a patient with high-grade internal carotid artery stenosis before and after surgery using DSC-MRI.
