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.
