自1979年有作者使用增强CT来评估脑灌注后,90年代则开始应用脑CT灌注像(computer tomography perfusion,CTP)判断急性脑梗死的溶栓治疗和用于观察肿瘤的对抗血管生成化疗的效果。近年来,由于多层螺旋CT的应用和软件系统的开发,CTP的研究和临床使用变得越来越现实,因其较低成本 Since the authors used enhanced CT to assess cerebral perfusion in 1979, the 90 th century began to evaluate cerebral thrombolysis in patients with acute cerebral infarction and CT angiochemotherapy for the treatment of tumors by computer tomography perfusion (CTP) . In recent years, due to the application of multi-slice spiral CT and the development of software systems, the research and clinical use of CTP have become more and more realistic due to its lower cost
