循证医学已证实,早期溶栓治疗,包括全身性用药或经动脉介入溶栓能显著改善缺血性卒中的预后,因此迫切需要建立快速准确的诊断方法。目前,卒中诊断依赖于病史、神经病学检查和神经影像学技术(包括头颅CT和MRI)。这些方法有一定的局限性,尤其是在卒中后最初的几个小时内,CT扫描只能检测出血性卒中,而对于缺血性卒中往往在病 Evidence-based medicine has shown that early thrombolytic therapy, including systemic medication or percutaneous thrombolysis can significantly improve the prognosis of ischemic stroke, therefore, there is an urgent need to establish a rapid and accurate diagnostic method. Currently, stroke diagnosis relies on medical history, neurological examination, and neuroimaging techniques (including cranial CT and MRI). These methods have some limitations, especially in the first few hours after stroke, CT scan can only detect hemorrhagic stroke, and ischemic stroke is often in the disease
