Comparison of Acetazolamide-Challenged CT Perfusion with Acetazolamide-Challenged SPECT in Moyamoya Patients
… correlating with cerebrovascular reserve (CVR) obtained by SPECT in moyamoya patients. Normalized baseline CTP parameters and their percent changes were calculated in 152 regions of interest (ROIs). On qualitative SPECT analysis, each ROI was classified as “impaired CVR” and “normal CVR” …

Identifying Patients at Risk for Hyperperfusion after Carotid Stenting Using CT Perfusion with Acetazolamide Challenge
… measurement of cerebrovascular reserve (CVR) by using CT perfusion (CTP) with acetazolamide (ACZ) challenge could identify patients at risk for hyperperfusion after CS. For 12 patients with symptomatic unilateral or bilateral carotid stenosis (> 70%), hemodynamic parameters including …

Identifying Patients for Carotid Artery Stenting : Feasibility of Acetazolamide - Challenged Dynamic CT Perfusion
To correlate quantitative cerebrovascular reserve calculated by acetazolamide - challenged CT perfusion with clinical symptoms in patients with high-grade (>70%) carotid stenosis and impaired cerebrovascular reserve who did not have evidence of embolic stroke. Thirty-seven patients diagnosed as …
