从1992年7月～1993年6月,作者对49例颅内动脉瘤和12例动静脉畸形(AVM)患者进行三维CT血管造影(3D—CTA)检查。静脉注射碘造影剂后,用快速扫描序列进行CT扫描获得最大数量的CT重建层面。通过计算机形成左到右、从前到后旋转180°的三维图像观察血管病变和周围血管及颅骨结构。对大型、不常见或诊断困难的脑血管病人增加DSA检查。 作者在讨论中指出30—CTA的危险性低损伤小,对大型和不常见脑血管病灶,能提供有价值的解剖资料。迅速观察血管病变与正常血管和颅底的解剖资料。迅速观察血管病变与正常血管和颅底的解
From July 1992 to June 1993, the authors performed 3D CT angiography (3D-CTA) in 49 patients with intracranial aneurysms and 12 patients with AVM. After intravenous iodine contrast agent, CT scanning was performed with a rapid scan sequence to obtain the maximum number of CT reconstructions. Left and right computerized left-right, rotated 180 ° from front to back three-dimensional images of vascular lesions and peripheral vascular and skull structure. To large, unusual or difficult to diagnose patients with increased DSA DSA examination. The authors pointed out in the discussion that 30-CTA is less dangerous and less damaging to large and less common cerebrovascular lesions and provides valuable anatomic information. Rapid observation of vascular lesions and normal blood vessels and skull base anatomical data. Rapid observation of vascular lesions and normal blood vessels and skull base solution
