Brain noncontrast computed tomography (CT), CT angiography, and magnetic resonance imaging have been used clinically for decades, and emergency physicians have a good understanding of their indications, the meaning of their results, and some facility with the interpretation of CT. However, brain CT perfusion (CTP) is relatively new and emergency physicians are less familiar with its basic concepts, indications, and role in managing patients with neurological emergencies.
We will review the parameters of clinical interest on a CTP report, and how to incorporate them into clinical decision-making.
Endovascular therapies paired with CTP have opened up a new frontier in stroke management for severely debilitated stroke patients. It is important for emergency physicians to have an understanding of CTP and how to use it clinically.
Taking care of patients with large-vessel occlusions is multidisciplinary, and emergency physicians need to understand CTP imaging and its clinical utility.
脑部非对比 CT（CT）、CT 血管造影和磁共振成像已在临床上使用了数十年，急诊医师对其适应证、结果意义和 CT 解读有一定的了解。然而，脑 CT 灌注（CTP）相对较新，急诊医师对其基本概念、适应证及其在神经急症患者管理中的作用了解较少。
我们将回顾 CTP 报告中临床关注的参数，以及如何将其纳入临床决策。
与 CTP 相结合的血管内治疗为严重衰弱的中风患者的中风管理开辟了一个新的领域。急诊医师了解 CTP 及其临床应用非常重要。
照顾大血管闭塞的患者是多学科的，急诊医师需要了解 CTP 成像及其临床应用。
