Recent rapid advances in endovascular treatment for acute ischemic stroke highlight the crucial role of neuroimaging especially multimodal computed tomography (CT) including CT perfusion in stroke triage and management decisions. With an increasing focus on changes in cerebral physiology along with time-based matrices in clinical decisions for acute ischemic stroke, CT perfusion provides a rapid and practical modality for assessment and identification of salvageable tissue at risk and infarct core and provides a better understanding of the changes in cerebral physiology. Although there are challenges with the lack of standardization and accuracy of quantitative assessment, CT perfusion is evolving as a cornerstone for imaging-based strategies in the rapid management of acute ischemic stroke.
急性缺血性卒中血管内治疗的近期快速进展凸显了神经影像学尤其是多模态计算机断层扫描（CT）包括CT灌注在卒中分诊和管理决策中的关键作用。随着急性缺血性卒中临床决策中对脑生理变化以及基于时间矩阵的关注度不断提高，CT灌注为评估和识别有风险的可挽救组织及梗死核心提供了一种快速且实用的方法，并且能更好地理解脑生理变化。尽管在定量评估的标准化和准确性方面存在挑战，但CT灌注正逐渐成为急性缺血性卒中快速管理中基于影像学策略的基石。
