CT-Based Assessment of Acute Stroke: CT, CT Angiography, and Xenon-Enhanced CT Cerebral Blood Flow

Abstract

The combination of CT, CTA, and Xe/CT CBF does define potentially significant subgroups of patients. The utility of this classification is supported by the observation that CTA and XeCT CBF are superior to CT alone in predicting infarction on follow-up CT and clinical outcome. This information may be useful in selecting patients for acute-stroke treatment.
