CT Angiography in Acute Ischemic Stroke
Background and Purpose—We sought to evaluate the ability of CT angiography (CTA) to determine vessel occlusion before acute stroke treatment and to predict its impact on patient outcome. Methods—Consecutive patients with acute focal neurological deficits received immediate brain CTA. Occlusion on CTA was correlated with other neuroimaging studies and clinical outcome. Results—Diagnostic CTA was...
متن کاملPotential of CT angiography in acute ischemic stroke.
PURPOSE To study the ability of CT angiography to show intracranial arterial occlusion and collateral blood flow in patients with acute stroke. METHODS Twenty-one patients with acute nonhemorrhagic stroke were studied prospectively with conventional CT, CT angiography, and digital subtraction angiography. On the basis of CT angiographic findings, two neuroradiologists independently assessed t...
متن کاملIdentification of infarct core and penumbra in acute stroke using CT perfusion source images.
BACKGROUND AND PURPOSE CT perfusion (CTP) mapping has been reported to be useful in the differentiation of the infarct core and ischemic penumbra. However, the value of the CTP source imaging (CTP-SI) during the arterial and venous phases has not been fully investigated. The purpose of this study was to develop a CTP-SI methodology for acute ischemic stroke and compare its efficacy with cerebra...
متن کاملAssessment of intracranial collaterals on CT angiography in anterior circulation acute ischemic stroke.
BACKGROUND AND PURPOSE Intracranial collaterals influence the prognosis of patients treated with intravenous tissue plasminogen activator in acute anterior circulation ischemic stroke. We compared the methods of scoring collaterals on pre-tPA brain CT angiography for predicting functional outcomes in acute anterior circulation ischemic stroke. MATERIALS AND METHODS Two hundred consecutive pat...
متن کاملCollateral vessels on CT angiography predict outcome in acute ischemic stroke.
BACKGROUND AND PURPOSE Despite the abundance of emerging multimodal imaging techniques in the field of stroke, there is a paucity of data demonstrating a strong correlation between imaging findings and clinical outcome. This study explored how proximal arterial occlusions alter flow in collateral vessels and whether occlusion or extent of collaterals correlates with prehospital symptoms of fluc...
