研究目的:

验证使用简单磁共振平扫序列(DWI小梗死核心、多发散在梗死灶和FLAIR慢血流征等特征性表现)结合磁共振血管造影与进行复杂灌注成像进行取栓术前的等效性,验证使用简单术前评价进行取栓手术的安全性有效性。初步建立符合我国国情的超时间窗(6-12小时)取栓术前评价标准,使取栓流程更加简单快速安全有效从而让更多的脑梗患者受益,实现良好的社会经济效益。  

Objectives of Study:

To verify the equivalence of using simple magnetic resonance plain scan sequences (characteristic manifestations of DWI small infarct core, multiple divergent infarcts and FLAIR slow blood flow signs) combined with magnetic resonance angiography and complex perfusion imaging for prethrombectomy assessment; To verify the safety and effectiveness of using a simple preoperative evaluation for thrombectomy. To preliminarily establish a broadened therapeutic window(6-12 hours) pre-operative evaluation standard for thrombectomy in line with China's national conditions, and make the thrombectomy process simpler, faster, safer and more effective, to benefit more patients with cerebral infarction and achieve good social and economic benefits.
