Improving Cardiovascular Risk Assessment with CT Coronary Angiography and Myocardial CT Perfusion
… atherosclerosis, calcification and myocardial perfusion are necessary to determine future cardiovascular risk in various clinical settings. CT coronary angiography (CTCA) and myocardial CT perfusion (CTP) are promising techniques for the assessment of these factors. This thesis is comprised of …

Comparison of Acetazolamide-Challenged CT Perfusion with Acetazolamide-Challenged SPECT in Moyamoya Patients
CT perfusion (CTP) is 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. …

Identifying Patients for Carotid Artery Stenting : Feasibility of Acetazolamide - Challenged Dynamic CT Perfusion
… 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 unilateral severe carotid stenosis and 10 …

Identifying Patients at Risk for Hyperperfusion after Carotid Stenting Using CT Perfusion with Acetazolamide Challenge
Hyperperfusion syndrome can occur in patients with preprocedural cerebral hemodynamic impairment who candidate for carotid stent. We investigated whether preprocedural measurement of cerebrovascular reserve (CVR) by using CT perfusion (CTP) with acetazolamide (ACZ) challenge could identify patients …

Quantitative Cerebrovascular Reserve Measured by Acetazolamide-Challenged Dynamic CT Perfusion in Ischemic Adult Moyamoya Disease : Initial Experience with Angiographic Correlation
CT perfusion is a much more readily accessible imaging method to assess cerebral hemodynamic status than single-photon emission CT. We prospectively assessed quantitative cerebrovascular reserve by using acetazolamide (ACZ)-challenged CT perfusion for evaluating hemodynamic impairment in ischemic …

Role of non-enhanced CT characteristics for differentiating reversible and irreversible brain tissue injury and estimating the tissue fate in acute ischaemic stroke
… based on advanced imaging techniques such as CT perfusion and MRI. However, the universal availability of these techniques is limited. Non-enhanced computed tomography (NECT) is the most widely accessible imaging technique and mainly used to exclude contraindications to treatment, such as …
