Spiral CT was performed in 9 patients with 13 cerebral aneurysms known from angiography. All lesions were detected by spiral CT, the smallest lesion measuring 3 mm in diameter. The neck of the aneurysm and the anatomical relations could be determined very accurately in all cases. Advantages of spiral CT over magnetic resonance angiography include: the short examination time, the independence of flow rate and cardiac output, and the excellent visualisation of calcification, thrombus and the bony landmarks. Disadvantages are the necessity of iodinated contrast media, the long postprocessing and reconstruction time and the possibility of overlap from bone and venous blood.
对9例经血管造影确诊有13个脑动脉瘤的患者进行了螺旋CT检查。所有病变均被螺旋CT检测到，最小的病变直径为3毫米。在所有病例中，都能非常准确地确定动脉瘤的颈部及解剖关系。螺旋CT相对于磁共振血管造影的优势包括：检查时间短、不依赖流速和心输出量，以及对钙化、血栓和骨性标志的良好可视化。缺点是需要使用碘化造影剂、后处理和重建时间长，以及存在骨骼和静脉血重叠的可能性。
