In 20 patients with known or suspected supratentorial arteriovenous malformations, an attempt was made to see how far CT angiography with 3-dimensional reconstructions is able to make a diagnosis and to differentiate the various components of the angioma. Spiral CT was performed following an intravenous bolus injection of 60-80 ml of iodine containing contrast medium. In all patients the diagnosis was confirmed by intra-arterial DSA of the vertebral vessels. In 13 patients, av malformations could be diagnosed following multiplanar 3-D reconstructions which agreed with the findings on DSA. The large supplying vessels, the nidus and the large draining veins could be defined with certainty. In 6 patients follow-up examination after embolisation was performed. The results could be demonstrated in three dimensions and the success of treatment could be documented unequivocally. CT angiography with 3-D reconstruction is able to supply important information in the majority of intracranial av malformations, both during initial investigation and following treatment.
对20例已知或疑似幕上动静脉畸形的患者进行了研究，以探讨三维重建CT血管造影在多大程度上能够作出诊断并区分血管瘤的不同组成部分。在静脉推注60 - 80毫升含碘造影剂后进行螺旋CT扫描。所有患者均通过椎动脉的动脉内数字减影血管造影（DSA）确诊。13例患者通过多平面三维重建能够诊断出动静脉畸形，其结果与DSA检查结果一致。能够明确界定粗大的供血血管、畸形血管团和粗大的引流静脉。6例患者在栓塞治疗后进行了随访检查。结果能够以三维形式显示，治疗的成功与否能够得到明确记录。三维重建CT血管造影在大多数颅内动静脉畸形的初始检查和治疗后均能提供重要信息。
