摘　　要：目的:评价三维增强MR血管造影(3D CE-MRA)在颅内动脉瘤诊断中的价值及准确性。方法:选择51例动脉瘤患者中同时行3D CE-MRA、三维时间飞越法MR血管造影(3D TOF-MRA)检查的27例动脉瘤患者,所有患者经DSA检查确诊。比较3D CE-MRA和3D TOF-MRA在显示动脉瘤及动脉瘤形态、瘤颈、载瘤动脉及瘤腔血栓能力上的优劣。结果:27例患者检出29个动脉瘤,3D CE-MRA和3D TOF-MRA的敏感性分别是100%(29/29),86%(25/29)。在动脉瘤形态,瘤颈形状及载瘤血管的显示上3D CE-MRA优于3D TOF-MRA(P<0.01),瘤腔血栓的显示上二者无差异(P>0.05)。结论:3D CE-MRA是一种快速有效、无创的诊断颅内动脉瘤的方法。Objective： To assess the clinical value and accuracy of three-dimensional contrast-enhanced magnetic resonance angiography （3D CE-MRA ） in the detection of intracranial aneurysms. Methods： Three-dimensional time of fight magnetic resonance angiography（3D TOF-MRA） and 3D CE-MRA was performed in 27 of 51 patients with intracranial aneurysms, all patients were confirmed by DSA. 3D CE-MRA images and 3D TOF-MRA images were compared for detection of a- neurysms and morphology of the aneurysm, neck and the relationship of the parent artery. Results： Twenty-nine aneurysms were detected in 27 patients, the sensitivity in the detection of aneurysms was 100%（29 of 29） for 3D CE-MRA and 86%（25 of 29） for 3D TOF-MRA. In the depiction morphology of aneurysm, neck and parent artery, 3D CE-MRA was significantly better than 3D TOF-MRA（P〈0.01）; In the demonstration of the thrombus in aneurysmal sac, there was no significant difference between 3D CE-MRA and 3D TOF-MRA （P〉0.05）. Conclusion： 3D CE-MRA is a fast, efficient, and noninvasive imaging method in diagnosing intracranial aneurysms.
