Increasing use of computed tomographic perfusion and computed tomographic angiograms in acute ischemic stroke from 2006 to 2010.
BACKGROUND AND PURPOSE Our objective was to study nationwide utilization trends of computed tomographic (CT) angiogram (CTA) and CT perfusion (CTP) in acute ischemic stroke and particularly in the context of use of reperfusion therapies. METHODS We reviewed the Premier Perspective Database for ischemic stroke-related hospitalizations of adult patients during a 5-year period, 2006 to 2010. Use...
متن کاملEvaluation of early computed tomographic findings in acute ischemic stroke.
BACKGROUND AND PURPOSE Detection of large, hypoattenuated brain-tissue volume on hyperacute CT scan has been suggested as an exclusion criterion for early intravenous tissue plasminogen activator (IV-tPA) treatment. This study assessed the reliability of detection for these findings and their relationship to outcome. METHODS Fifty hyperacute CT scans (<6 hours after ictus) were selected from ...
متن کاملUsing standard first-pass perfusion computed tomographic data to evaluate collateral flow in acute ischemic stroke.
BACKGROUND AND PURPOSE The study aims to determine whether volume transfer constant (K(trans)) maps calculated from first-pass perfusion computed tomographic data are a biomarker of cerebral collateral circulation and predict the clinical outcome in acute ischemic stroke caused by proximal arterial occlusion. METHODS Consecutive patients with acute occlusion of the middle cerebral artery who ...
متن کاملValue of Computed Tomographic Perfusion-Based Patient Selection for Intra-Arterial Acute Ischemic Stroke Treatment.
BACKGROUND AND PURPOSE The utility of computed tomographic perfusion (CTP)-based patient selection for intra-arterial treatment of acute ischemic stroke has not been proven in randomized trials and requires further study in a cohort that was not selected based on CTP. Our objective was to study the relationship between CTP-derived parameters and outcome and treatment effect in patients with acu...
متن کاملTime-Dependent Computed Tomographic Perfusion Thresholds for Patients With Acute Ischemic Stroke.
BACKGROUND AND PURPOSE Among patients with acute ischemic stroke, we determine computed tomographic perfusion (CTP) thresholds associated with follow-up infarction at different stroke onset-to-CTP and CTP-to-reperfusion times. METHODS Acute ischemic stroke patients with occlusion on computed tomographic angiography were acutely imaged with CTP. Noncontrast computed tomography and magnectic re...
