Title: Comparative Study in the Diagnosis of Intracranial Aneurysms with 64 Slice CTA-and 3D DSA
Abstract: Objective To evaluate the role of 64 slice computed tomography angiography maximum intensity projection(CTA,MIP),computed tomography angiography volume rendering(CTA,VR) and 3 dimensional digital subtraction angiogtaphy(3D-DSA))in the diagnosis of intracranial aneurysms.Materials and Methods The CT and DSA imaging findings of 32 patients with aneurysms were retrospectively analyzed and compared.Results 40 aneurysms in 32 patients were found by DSA and/or operation.35 aneurysms were found by CTA MIP.37 aneurysms were found by CTA VR.39 aneurysms were found by DSA.11 aneurysms were at posterior communicating artery,16 aneurysms at middle cerebral artery,4 aneurysms at basilar artery,1 aneurysms at vertebary artery,2 aneurysms at anterior cerebral artery,3 aneurysms at posterior cerebral artery,3 aneurysms at internal carotid artery.There was no significant difference in detecting aneurysms between CTA and 3D DSA.Conclusion CTA MIP,CTA VR and 3D-DSA examination have their own advantage in diagnosis of intracranial aneurysms.CTA can be used as the method in screening intracranial aneurysms for surgery and interventional therapy.
