目的：对17例烟雾病病人的数字减影脑血管造影(DSA)和CT征象进行分析，总结其表现。材料和方法：17例均进行了DSA检查及CT扫描，其中14例行高清晰螺旋CT扫描，5例行薄层增强扫描。结果：按日本厚生省的诊断标准，16例为确诊病例，1例为可疑病例。颈内动脉(ICA)病变主要为狭窄，大脑前动脉(ACA)、大脑中动脉(MCA)病变主要为闭塞。烟雾血管多位于脑底基底节区，较晚期病人可见眶顶或其它部位烟雾血管，而基底节区烟雾血管可消失。结论：对本病CT无特异性，只起提示作用。对于螺旋CT增强病人应注意其基底池层面大血管有无及血管异常强化影征象，有较好的提示作用。
Objective: To analyze the digital subtraction angiography (DSA) and CT signs of 17 patients with moyamoya disease and summarize their manifestations. MATERIALS AND METHODS: Twenty-seven patients underwent DSA and CT scans. Of them, 14 patients underwent high-resolution helical CT scan and 5 patients underwent thin-section contrast-enhanced scan. Results: According to the diagnostic criteria of Japan’s Ministry of Health, 16 cases were diagnosed and 1 case was suspicious cases. Internal carotid artery (ICA) lesions mainly stenosis, anterior cerebral artery (ACA), middle cerebral artery (MCA) lesions mainly occlusion. Smoke and blood vessels in the basal ganglia more than the brain, the more advanced patients with orbital roof or other parts of the smoke and blood vessels, and basal ganglia smoke and blood vessels can disappear. Conclusion: No specific CT on the disease, only played a hint. For spiral CT enhanced patients should pay attention to its basal pool surface vessel and vascular abnormal enhancement phenomenon, a good hint.
