China is entering into an aging society, and the incidence of hypertension and atherosclerosis were increased year by year. The incidence of transient ischemic attack (TIA) patients with carotid stenosis increased year by year. Carotid artery stenosis or occlusion can cause reduction of local brain tissue perfusion resulting from TIA. CT cerebral perfusion imaging and SPECT could detect earlier the chronic hyper fusion of carotid stenosis TIA, forecast risk coefficient and intervention and prevent the occurrence of cerebral infarction, to evaluate effect of carotid endarterectomy and carotid s carotid artery stenting. It is very important to monitor cerebral hemodynamic changes. The technology has the features of blood infusion situation, advantages, curative effect evaluation and development trend in carotid stenosis TIA reviewed by CT perfusion imaging and SPECT.%我国正在步入老龄化社会，高血压、动脉粥样硬化的发病率逐年增高，颈动脉狭窄性短暂性脑缺血发作(TIA)的患者发病率也逐年上升。颈动脉的狭窄或闭塞能够引起局部脑组织灌注减少从而导致TIA的发生。CT脑灌注成像和SPECT能够在早期发现颈动脉狭窄性TIA的慢性低灌注状态，及早预测发生风险系数、干预治疗和防止脑梗塞的发生，评价颈动脉内膜剥脱术和颈动脉支架置入术的手术疗效，监测脑血流动力学变化情况具有重要价值。本研究在文献评阅的基础上，综述CT脑灌注成像、SPECT在颈动脉狭窄性TIA技术的应用，具备血流灌注情况、优势、疗效评估及发展趋势。
