Our purpose was to assess the value of three-dimensional (3D) CT angiography in the diagnosis of moyamoya disease. We studied seven patients with moyamoya disease proved by conventional angiography. Three-dimensional (3D) CT angiography was performed using rapid sequence or helical (spiral) scanning in conjunction with a bolus injection of intravenous contrast medium. All seven patients could be diagnosed as having moyamoya disease on the basis of the following 3D CT angiographic findings: poor visualisation of the main trunks and/or major branches of anterior and middle cerebral arteries (7 patients); dilated leptomeningeal anastomotic channels from the posterior cerebral arteries (4); and demonstration of "moyamoya vessels" in the basal ganglia (2). Although conventional angiography remains the principal imaging technique for demonstrating anatomical changes in detail, less invasive 3D CT angiography provides a solid means of diagnosing moyamoya disease when it is suspected on CT, MRI, or clinical grounds.
我们的目的是评估三维（3D）CT血管造影在烟雾病诊断中的价值。我们研究了7例经传统血管造影证实为烟雾病的患者。采用快速序列或螺旋扫描结合静脉注射造影剂进行三维（3D）CT血管造影。基于以下3D CT血管造影表现，所有7例患者均可诊断为烟雾病：大脑前动脉和大脑中动脉主干和/或主要分支显示不佳（7例）；大脑后动脉发出的软脑膜吻合支增粗（4例）；基底节区显示“烟雾血管”（2例）。虽然传统血管造影仍然是详细显示解剖结构变化的主要成像技术，但当根据CT、MRI或临床情况怀疑烟雾病时，侵入性较小的3D CT血管造影为诊断烟雾病提供了可靠的方法。
