The clinical values of multi-slice spiral CT angiography in diagnosis of aortic aneurysms

Objective:To evaluate the clinical values of multi-slice spiral CT angiography(MSCTA) in diagnosing aortic aneurysms.Methods:Twenty-one patients with aortic aneurysms were performed by spiral CT angiography,shaded surfacedisplay(SSD),multiplanar reformation(MPR),maximum intensity projection(MIP),volume rendering(VR) were sued to reconstruct the image of axial view.Results:SSD,MPR showed the panorama of aortic lesion,extent and size of aneurysm,intimae flake and the relation between it and arterial branches.The location of crevasse was showed;MIP could show the calcification and extend of aneurysm.Lesion was reconstructed and observed on any angle.The intratumorally thrombus and crevasse was showed clearly;MPR could display the mural thrombus,intimae flake and the true and false dissecting aneurysm.Conclusion:The technology of MSCTA for aortic aneurysm diseases provides a safe and reliable means of diagnosis,clinical treatment has important significance.
