摘　　要：【目的】评价三维CT血管成像(3D-CTA)与DSA在瘤诊断和治疗颅内动脉中的应用价值。【方法】52例患者行3D-CTA与DSA检查,两者对照研究并以术中发现为准评估图像质量。【结果】本组动脉瘤44个,3D-CTA准确检出40个,DSA准确检出43个,两者检出能力无显著差异(P>0.05);根据术中发现,3D-CTA在瘤壁钙化、载瘤动脉的显示、瘤周解剖标志等方面,明显优于DSA(P<0.05)。【结论】随着CT机及软件的更新,3D-CTA可能取代DSA成为颅内动脉瘤诊断和治疗的首选。[ Objective ] To evaluate the value of 3D-CTA and DSA as the diagnostic and treatment way for intracranial aneurysm. [Methods] Totally 52 patients underwent 3D-CTA and DSA. The image quality of 3D-CTA and DSA were assessed according to surgical findings. [ Results ] A total of 44 aneurysms in this study, 40 aneurysms were detected by 3D-CTA, 43 aneurysms were detected by DSA. There was no statistical difference in detecting ability between 3D-CTA and DSA （P〉0.05）,3D-CTA were superior to DSA for depicting aneurysm-wall calcification, parentartery, anatomic landmark surrounding aneurysm （P 〈 0.05）. [Conclusion] With CT machine and software renew, 3D-CTA will probably displace DSA as the first selection in diagnostic and treatment way for intracranial aneurysm.
