Title: Clinical application of three diamensions computed tomography angiography in diagnosing intracranial aneurysms
Abstract: Objective To investigate the diagnostic value of three-dimensional computed tomographic angiography(3D-CTA) in intracranial aneurysms. Methods 3D-CTA and digital subtraction angiography(DSA) examinations were performed in 38 patients with subarachnoid hemorrhage or highly suspected to be intracranial aneurysm diagnosed by CT.The 3DCT images from 3D-CTA and DSA were obtained.The manifestations of intracranial arteries,detection of intracranial aneurysm and relationship between aneurysm and parent artery or crinial bone were analyzed. ResultsCTA images showed the intracranial arterial trunk and branchs as clear as DSA.A total of 42 intracranial aneurysms in 35 cases was diagnosed definitely,of which 40 aneurysms were detected by DSA and 41 aneurysms were detected by CTA.The appearance of aneurysm neck and stereochemical structure of 25 parent arteries were clearly showed by CTA,but the appearance of aneurysm neck was clearly showed only in 8 aneurysms by DSA(P0.05). Conclusion 3D-CTA can be used as a conventiobal radiological method to find aneurysms and reexamine them after surgery and may provide a reference for selecting the regime of clinical treatment.
