Which CT Perfusion Parameter Best Reflects Cerebrovascular Reserve?: Correlation of Acetazolamide-Challenged CT Perfusion with Single-Photon Emission CT in Moyamoya Patients

摘要

BACKGROUND AND PURPOSE: CT perfusion (CTP) is a more readily accessible method for evaluation of cerebral perfusion than single-photon emission CT (SPECT). We assessed whether there is any resting or drug-challenged CTP parameter correlating with cerebrovascular reserve (CVR) obtained by SPECT in Moyamoya patients.
