title: The Accuracy and Usefulness of 3D-DSA and 3D-CT Angiography for Cerebral Aneurysms.
abstract: For evaluation of intracranial cerebral aneurysms, three-dimensional (3D) digital subtraction angiography (DSA) and 3D-computed tomographic angiography (CTA) were demonstrated in fifteen patients. The diagnostic accuracy of preoperative 3D-CTA is equal to that of 3D-DSA except for the case with a dissecting aneurysm. The virtual images of 3D-CTA were well correlated with surgical findings. In endovascular treatment of intracranial aneurysms, 3D-DSA had an obvious advantage in obtaining the best working angle of the C-arm. The major branches originating from the dome were depicted on 3D-DSA in two cases that could not be judged on 3D-CTA. The aim of the present study was to verify the difference between 3D-DSA and 3D-CTA for evaluation of intracranial aneurysms.
