回顾了基底动脉穿通支分布沿着脑梗死的CT表现，并与脑血管造影进行对照。根据尸体微血管造影所示的三维分布知识，单独显示穿支动脉区域内的血管。在研究的第一部分中，检查了内侧纹动脉（MSA）和外侧纹动脉（LSA）的供血区域。沿着MSA分支的梗死通常累及纹状体的前下部，紧邻侧脑室前角最下部的后外侧。沿LSA分支的分支沿着向上、后覆盖MSA的区域，并累及纹状体后外侧区。临床和神经放射学的相关性进行了讨论。
Computed tomographic (CT) manifestations of cerebral infarction along the distribution of the basal perforating arteries were reviewed in correlation with cerebral angiography. Infarcts in the territories of perforators were demonstrated individually based on knowledge of their three-dimensional distribution as demonstrated by microangiography of cadavers. In Part I of the study, the areas supplied by the medial (MSA) and lateral striate arteries (LSA) were examined. Infarction along the branches of the MSA usually involved the antero-inferior portion of the corpus striatum, immediately posterolateral to the most inferior part of the frontal horn of the lateral ventricle. Infarcts along the branches of the LSA abutted the territory of the MSA posteriorly and superiorly and involved the posterolateral region of the corpus striatum. Clinical and neuroradiological correlations are discussed.
