Abstract:
Objective: To research three-dimensional computed tomography angiography (3D-CTA) combined three-dimensional digital subtraction angiography (3D-DSA) in the diagnosis of intracranial aneurysms. Methods: 3D-CTA and 3D-DSA were performed in 27 cases with Highly suspected in patients with intracranial aneurysms, And compared with the final outcome of surgery. To evaluate 3D-CTA and 3D-DSA in the detection rate of aneurysms, three-dimensional shape and spatial relations ability to display. Research 3D-CTA combined 3D-DSA in the diagnosis of intracranial aneurysms. Results: Twenty-seven cases of suspected patients, 25 cases of surgical treatment of confirmed aneurysms, 28 aneurysms found. 3D-CTA and 3D-DSA rate of aneurysms was no significant difference. 3D-CTA of the aneurysm can be accurately detected clearly shows its three-dimensional shape and spatial relationship with the surrounding skull, 3D-DSA for aneurysm neck, the tumor and the aneurysm and parent artery relationship shows clear and accurate. Conclusion: Imaging of intracranial aneurysm diagnosis, 3D-CTA and 3D-DSA have their respective advantages, combined two methods can improve the detection rate of aneurysms. 3D-CTA combined 3D-DSA have support of design for operation.
