多年来,急性脑梗死的早期诊断和治疗一直是临床关注的问题。随着溶栓技术的改进以及溶栓药物的发展,超早期溶栓已经成为治疗脑梗死的有效方法,而这一方法成功的关键在于超早期内发现并挽救缺血半暗带,故常规的CT和MRI检查已不能满足目前临床的要求。磁共振技术与传统X线技术完 Over the years, the early diagnosis and treatment of acute cerebral infarction has been a clinical concern. With the improvement of thrombolytic technology and the development of thrombolytic drugs, ultra-early thrombolysis has become an effective method for the treatment of cerebral infarction. The key to the success of this method lies in the discovery and rescue of ischemic penumbra in an ultra-early stage. Therefore, conventional CT and MRI can no longer meet the current clinical requirements. End of magnetic resonance technology and traditional X-ray technology
