摘要 缺血性脑血管病主要是由于脑血管动脉粥样硬化造成的急性、慢性脑损害。动脉粥样硬化造成的血管壁损害是缺血性脑血管病最主要的病因。正电子发射断层显像术(PET)利用放射性核素标记的化合物作为探针,可以从炎症、乏氧、微钙化及新生血管生成多个方面评估动脉粥样硬化斑块破裂的风险,可以从脑血流量阈值、乏氧状态、葡萄糖代谢情况评估急性脑梗死患者的缺血半暗带和梗死核心,可以从神经细胞内线粒体功能状态、神经元γ氨基丁酸的含量、小胶质细胞的活化情况评估急性脑梗死后神经细胞损伤和周围炎症反应,还可以从脑血流灌注情况、脑血管储备功能及脑氧代谢方面评估脑动脉粥样硬化性狭窄闭塞和烟雾病造成的慢性脑损害的严重程度及预后。
