The purposes of this article are to describe the important role of the medullary arteries in the pathogenesis of cerebral vascular disease and to present a classification of MRI findings of ischemic white matter lesions for use in elucidating pathogenesis.
From the viewpoint of the anatomy of the medullary arteries, the pattern of medullary artery-related ischemic changes and infarcts can be classified into four types: 1, ischemic leukoaraiosis; 2, infarcts involving individual medullary arteries; 3, watershed infarcts; and 4, territorial infarcts.
本文旨在描述髓质动脉在脑血管疾病发病机制中的重要作用，并提出用于阐明发病机制的缺血性白质病变的MRI表现分类。
从髓质动脉的解剖学角度来看，与髓质动脉相关的缺血性改变和梗死模式可分为四种类型：1，缺血性脑白质疏松症；2，累及单个髓质动脉的梗死；3，分水岭梗死；4，区域梗死。
