摘　　要：急性脑血管疾病是一组由各种病理因素引起脑部血管循环障碍的疾病,进而引起神经功能损伤,出现失语、眩晕、共济失调,严重者甚至发生死亡。因此,早期准确判断患者病情,对改善患者预后具有积极意义。CT灌注成像(CTPI)技术作为一种功能成像,能早期诊断急性缺血性脑卒中、急性自发性脑出血、急性高血压性脑出血、自发性蛛网膜下腔出血等急性脑血管疾病,并能从形态学和功能学上综合分析患者病情程度,为上述疾病的早期治疗提供合理有效的影像学依据。目前,临床缺乏CTPI诊断急性脑血管疾病的明确评估标准,有待未来的研究进一步规范。Acute cerebrovascular disease is a group of diseases caused by various pathological factors that cause cerebral vascular circulation disorders,which in turn cause neurological damage,causing patients to suffer from aphasia,dizziness,ataxia,and even death in severe cases.Therefore,early and accurate judgment of the patient′s condition has positive significance for improving the prognosis.As a functional imaging,CT perfusion imaging(CTPI)technology can early diagnose acute ischemic stroke,acute spontaneous cerebral hemorrhage,acute hypertensive cerebral hemorrhage,spontaneous subarachnoid hemorrhage and other acute cerebrovascular diseases,which can comprehensively analyze the degree of the patient′s condition from the morphological and functional aspects,and provide a reasonable and effective imaging basis for the early treatment of the above mentioned diseases.At present,there is a lack of clear evaluation criteria for CTPI diagnosis of acute cerebrovascular disease in clinical practice,and needs to be further standardized in future research.
