    [摘要] 无症状性脑梗死(ACI)是脑血管病的一种，其发病与年龄、高血压、颈动脉粥样硬化等多种因素相关。由于ACI并不表现出典型的症状和体征，常被医患双方忽视，大部分在体检时才被发现，此时患者脑实质已受损，甚至发生不可逆的病理改变，尽早检出并及时干预和治疗显得极为重要。如不及时控制ACI的危险因素，可增加症状性脑梗死、神经认知功能障碍和精神疾病的风险。目前，ACI多由磁共振成像(MRI)检出，高分辨率MRI可提高ACI的检出率，并降低其误诊率。

    [Abstract] Asymptomatic cerebral infarction (ACI) is a kind of cerebrovascular disease， which is associated with age， hypertension， carotid atherosclerosis and so on. Because of the ACI does not show typical symptoms and signs， both doctors and patients often ignore it， most of them are found by physical examination， at this time the patient's brain parenchyma has been damaged， and even irreversible pathological changes have happened. Early detection， intervention and treatment timely is extremely important. If not timely control the risk factors of ACI， it can increase the risk of cerebral infarction， neurocognitive dysfunction and mental illness. At present， ACI is detected mostly by MRI， high resolution MRI can improve the detection rate of ACI and reduce the misdiagnosis rate. ......
