The application of the progress in TIA of carotid diagnosis and treatment by low dose CT cerebral perfusion and SPECT / 中国医学装备

ABSTRACT

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.
