[摘要]近年来，随着对脑白质病变的深入研究，先进的影像学及生物化学检测方法被采用，脑白质病变的检出率得到了提升，预防和治疗取得了进展。缺血性脑白质病变是一种放射学的定义，描述在脑室旁、半卵圆中心的斑点状或斑片状CT低密度而颅脑磁共振的T2加权像及液体衰减反转恢复序列(FLAIR)均表现为高信号的病变。缺血性脑白质病变在老年人中的患病率高，并增加2倍痴呆及3倍脑卒中的风险，且随着社会的持续老龄化而造成更沉重的负担。本文就缺血性脑白质病变的诊治进展作一综述。

    [Abstract] Recently， with intensive studies of white matter lesions and development of imaging and biochemical detection techniques， the detection rate， prevention and treatment methods of white matter lesions have been remarkably improved. Ischemic white matter lesions are a neuroimaging definition and indicated by low-density spotted or patchy near the periventricular white matter and semi-oval center on CT images and hyperintensities on T2-weighted or fluid-attenuated inversion recovery (FLAIR) images. Ischemic white matter lesions have a higher prevalence in the elderly and multiply double the risk of dementia and triple stroke ......
