Abstract
CTP has a growing role in evaluating stroke. It can be performed immediately following NCCT and has advantages of accessibility and speed. Differentiation of salvageable ischemic penumbra from unsalvageable core infarct may help identify patients most likely to benefit from thrombectomy or thrombolysis. Still, CTP interpretation can be complex. We review normal and ischemic perfusion patterns followed by an illustrative series of technical/diagnostic challenges of CTP interpretation in the setting of acute stroke syndromes.
摘要
CTP 在评估中风方面的作用日益凸显。它可以在 NCCT 之后立即进行，具有便捷性和快速性的优势。鉴别可挽救的缺血半暗带与不可挽救的核心梗死灶，有助于确定最有可能从取栓或溶栓治疗中获益的患者。尽管如此，CTP 解读可能较为复杂。我们首先回顾了正常和缺血灌注模式，然后展示了一系列急性脑卒中综合征背景下 CTP 解读的技术/诊断挑战实例。
