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。
Abstract
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 aneurysms 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.
