摘要
脑白质疏松是多种原因造成的,CT表现为脑室周围或皮质下区(半卵圆中心)弥漫性低密度带,在MRI T2加权像上为弥漫性高信号。小动脉病变导致的白质纤维脱髓鞘是发生白质疏松的主要原因之一。文章对脑白质疏松的临床表现、影像学、病理学特点及其发病机制进行了综述。
Leukoaraiosis is caused by a variety of diseases. It presents diffuse low density areas in periventricular and subcortical areas （centrum semiovale） on CT or presents diffuse high sig- nals on T2-weighted imaging. Demyelination of white matter fibers caused by arteriopathy is one of the major causes of leukoaraiosis. This article reviews the clinical manifestation, imaging and pathological features of leukoaraiosis, as well as its pathogenesis.
