Clinical Applied Value of Multi-slice CT Angiography in Diagnosis of Cerebral Aneurysms / 实用放射学杂志

ABSTRACT

Objective To evaluate the diagnostic value of multi-slice CTA(MSCTA) in cerebral aneurysms.Methods 15 patients with cerebral aneurysms were undergone MSCTA,of which,DSA were performed in 5 cases,and Gnglielmi detachable coil were performed in 2 cases . The images of 15 patients were processed with maximum intensity projection ( MIP ) , volume rendering ( VR ) and multiple planar reconstruction ( MPR ) .Results 16 cerebral aneurysms in 15 patients were found by MSCTA , the location of aneurysms was in the vertebral artery in 2,in the cerebral arterial circle in 5,in the anterior cerebral artery in 5 ,and in the middle cerebral artery in 3.DSA displayed 4 cerebral aneurysms in 5. 3D-CTA imaging and MPR combined with original transect images and multi-angle observation wereof great advantageous for diagnosis. The position, size and width of the fundus of cerebral aneurysms in 5 patients displayed by CTA wereaccordant with the results of DSA.Conclusion MSCTA can display cerebral aneurysms clearly. 3D-CTA combined with MPR and original images can make diagnosis more accurate and objective, and provide valuable information for surgery or interventional therapy.
