Abstract:
Objective To evaluate the utility of three-dimensional digital subtraction angiography(3D-DSA) in the diagnosis of cerebral vascular diseases.Methods Seventy-one patients suspected and diagnosed with cerebral vascular diseases underwent conventional DSA and 3D-DSA. Three-dimensional (3-D) reconstructed images were obtained at a separate advantage 4.0 workstation after the rotational images were transferred. The available visualization techniques included maximum intensity projection (MIP), shaded surface display (SSD), and virtual angioscopy (VA). Results Sixty-four aneurysms were found in 44 cases. Nineteen cases were diagnosed as cerebral arteriovenous malformation (AVM) and 8 cases of cerebral ischemia were due to cerebral vascular stenosis (internal carotid artery in 6 cases and occlusion of anterior cerebral artery in 2 cases).Conclusions 3D-DSA is reliable, fast and safe for diagnosis of cerebral vascular diseases, especially involving intracanal areurysms AVM and vascular stenosis.
