无症状脑梗死(SCI)是指无卒中病史,无明确神经系统定位体征,由影像学(头颅CT或MRI)检查或尸检发现的梗死灶;随着影像学技术的提高,发现SCI广泛存在。SCI与症状性脑梗死的危险因素关系密切,因此对其影像学特点及危险因素进行分析对脑梗死的防治意义重大。
Asymptomatic cerebral infarction (SCI) refers to the absence of a history of stroke, there is no clear signs of neurological localization, by imaging (CT or MRI) examination or autopsy found infarct; as imaging techniques to improve and found SCI widespread. SCI and the risk factors of symptomatic cerebral infarction are closely related, so the analysis of its imaging features and risk factors for the prevention and treatment of cerebral infarction is of great significance.
