随着CT和MRI等神经影像学检查广泛应用于临床,无症状性脑梗塞(asymptomatic infarction AI)的发现已不少见,且对AI的认识日益深入。本文通过观察60例AI病人,探讨其危险因素及影像学特点。 1 临床资料 1.1 一般资料:男42例,女18例,年龄42～82岁,平均63.6±4.4岁。<50岁4例,51～60岁13例,61～70岁28例,70岁以上15例。有高血压病史者39例,高脂血症20例,糖尿病8例,冠心病 With the widespread use of neuroimaging tests such as CT and MRI in clinical practice, the discovery of asymptomatic infarction (AI) is not uncommon and the understanding of AI is becoming more and more frequent. This article observed 60 cases of AI patients, to explore the risk factors and imaging features. 1 Clinical data 1.1 General Information: 42 males and 18 females, aged 42 to 82 years, mean 63.6 ± 4.4 years. 4 cases were <50 years old, 13 cases were 51-60 years old, 28 cases were 61-70 years old and 15 cases were over 70 years old. 39 cases of history of hypertension, 20 cases of hyperlipidemia, diabetes, 8 cases, coronary heart disease
