脑小血管病影像学特征研究进展

Neuroimaging markers of cerebral small vessel disease

脑小血管病是一组发生在脑小动脉、微动脉、小静脉、毛细血管的病因多样的病理过程。脑小血管病神经影像标志物主要包括:近期皮层下小梗死、假定血管源性的腔隙灶、假定血管源性的白质高信号、血管周围间隙、脑微出血和脑萎缩。在相关研究中,可部分量化其中一些影像标志物来进行分析。根据病因,可将脑小血管病进行分型,文章简述其中几个临床常见脑小血管病的影像特点。

Cerebral small vessel disease refers to a group of pathological processes with various aetiologies that affect the small arteries, arterioles, venules, and capillaries of the brain. Neuroimaging markers of cerebral small vessd disease include recent small subcortical infarct, lacune of presumed vascular origin, white matter hyperintensity of presumed vascular origin, perivascular space, cerebral microbleed and brain atroph Here are some quantitative measures of neuroimaging analysis in many researches. Different types of small vessel diseases could be established according to aetiology and pathology Some imaging features of some clinically common cerebral small vessel diseases are discussed.
