作者报导了７３例脑底动脉环闭塞症的ＤＳＡ、ＣＴ和ＭＲ表现，对照分析其诊断价值。本症ＤＳＡ表现为颈内动脉及其分支狭窄，闭塞，主要累及虹吸部Ｃ１－２段，大脑前，中动脉起始部。脑底部显示纲状异常血管影，有广泛烟雾状侧支循环形成，有时伴有颅内血肿。ＣＴ表现为多发性脑梗塞，平均显示散在性斑点状，片状低密度影。伴脑出血时显示高密度影。ＭＲ表现为病变区为斑片状，点状异常信号，显示长Ｔ１长Ｔ２信号，部分病例局部脑萎缩，脑沟变深变宽，无占位效应。作者对照分析它们各自特点，提出ＤＳＡ是诊断本症的安全可靠的首选检查方法。
The authors report 73 cases of cerebral artery occlusion of the DSA, CT and MR manifestations, the comparative analysis of its diagnostic value. DSA manifestations of this disease for the internal carotid artery and its branches stenosis, occlusion, mainly involving the siphon C1-2 section, the anterior cerebral artery, the beginning of the middle artery. Cerebral atypia showed abnormal blood vessels shadow, a wide range of smoke collateral circulation formation, sometimes accompanied by intracranial hematoma. CT showed multiple cerebral infarction, showing an average of scattered spots, flaky low density. With cerebral hemorrhage shows high density. MR showed lesions as patchy, punctate abnormal signals, showing long T1 long T2 signal, partial brain atrophy in some cases, deep groove becomes wider, no placeholder effect. Authors comparative analysis of their respective characteristics, proposed DSA is the safe and reliable diagnosis of the disease the preferred method of inspection.
