Quantitative Cerebrovascular Reserve Measured by Acetazolamide-Challenged Dynamic CT Perfusion in Ischemic Adult Moyamoya Disease : Initial Experience with Angiographic Correlation
… CT. We prospectively assessed quantitative cerebrovascular reserve by using acetazolamide (ACZ)-challenged CT perfusion for evaluating hemodynamic impairment in ischemic adult Moyamoya disease and compared it with angiographic findings. Sixteen adult patients with ischemic Moyamoya disease …

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 …

Comparison of Acetazolamide-Challenged CT Perfusion with Acetazolamide-Challenged SPECT in Moyamoya Patients
… drug-challenged CTP parameter 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 …

Identifying Patients at Risk for Hyperperfusion after Carotid Stenting Using CT Perfusion with Acetazolamide Challenge
… whether preprocedural 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 …

Development and Application of Magnetic Resonance Imaging Techniques for the Study of Exercise-Induced Angiogenesis in the Rat Brain
… to controls. This is consistent with a larger cerebrovascular reserve in the animals that have exercised as would be expected with a more dense capillary bed. In addition to reporting these results we have proposed novel techniques for both blood flow and volume imaging that can be used for …

Cerebrovascular and Ventilatory Function in Chronic Obstructive Pulmonary Disease
… of studies set out to define the ventilatory and cerebrovascular responses to acute alterations in PCO2 and PO2 in COPD patients, and the relationship to oxidative stress. A secondary focus was to characterize both cerebral and peripheral blood flow during exercise. The thesis begins by …

Cerebral blood flow in the non-human primate : an in vivo model and drug interventions
… found application in the clinical setting of cerebrovascular diseases such as migraine and dementia. Due to the similarities between humans and non-human primates with respect to their brains, both structurally and behaviourally, numerous studies have been conducted and several non-human …
