摘　　要：目的探讨三维CT血管造影(3D-CTA)在脊髓血管母细胞瘤中的应用价值,并与数字减影血管造影(DSA)进行对比。方法回顾性分析28例脊髓血管母细胞瘤的临床、影像学资料,其中13例行术前DSA检查,15例行术前、术后3D-CTA检查。结果 3D-CTA与DSA在肿瘤供血动脉的检出率(P=1.000)及图像质量(P=0.367)方面无统计学差异。然而,脊髓DSA所需对比剂剂量是3D-CTA的1.88倍,有效放射线剂量是3D-CTA的2.73倍,且操作所需时间(平均120 min)远长于3D-CTA操作时间(平均扫描时间1 min)。结论与DSA相比,3D-CTA具有无创、所需对比剂剂量低、辐射少、操作时间短、方便术后复查等优点,对脊髓血管母细胞瘤的手术指导及随访具有重要价值。Objective To assess the value of three-dimensional computed tomography angiography （3D-CTA） in the application of intraspinal hemangiohlastomas, compared with digital subtraction angiography （DSA）. Methods Clinical and imaging data of 38 patients with intraspinal hemangioblastomas were retrospectively studied. DSA was performed in 13 patients, and 3D-CTA was carried out in 15 patients. Results No significant difference was observed between 3d-CTA and DSA in the ability of identifying the feeding arteries （ P = 1. 000） and image qualities （ P〈0. 367）. However, compared with 3d-CTA, the effective X-ray dose of spinal DSA was 2.73 times higher and the mean amount of contrast media was 1.88 times higher. Spinal DSA was more time-consuming （mean 120 minutes） than 3d-CTA （the scanning time 1 minute）. No complication was observed after 3d-CTA while one patient developed acute paraparesis after DSA. Conclusion Compared with spinal DSA, 3d-CTA is a promising technique because of its noninvasiveness, time saving, lower X-ray dose delivering, less contrast media injecting, and accuracy in delineating the feeding arteries.
