Title: Diagnotic application of intracranial aneurysm by 64-detector row CT angiography
Abstract: Objective:To evaluate the diagnostic value of 64-detector row computed tomographic angiography(CTA) in intracranial aneurysm compared with the conventional intraarterial digital subtraction angiography(DSA).Methods:64-detector row CT angiography and DSA were performed in 29 patients with suspected intracranial aneurysms.Source images were got by GE light speed VCT scanner and were performed to reconstruct by MPR,VR,TS MIP.CTA reconstruction and DSA images were reviewed by 2 radiologists.Results:A total of 27 aneurysms were confirmed by DSA in 25 patients,in which two patients had two aneurysms.Compared with the results of DSA,26 cerebral aneurysms in 25 patients were found by CTA and I common carotid artery aneurysm was not diagnosed.The size, shape and parent vessel of aneurysm were clearly displayed by CTA.The neck of aneurysm in 3 cases was not displayed by DSA but was in all cases by CTA.Conclusion:64-detector row CTA has very high value in diagnosis,of intracranial aneurysms and has unique advantage in displaying the neck of aneurysm,providing precistic diagnose and treament information.
