Abstract：Objective: To explore the value of multi-slice spiral CT angiography in the diagnosis of aortic atherosclerosis, aortic dissection and aortic aneurysm. Methods: 63 patients suffered from aortic disease were scanned by CT angiography with the 6-slice spiral CT, and the data was transferred to the workstation for image post-processing including multiple planar reformation(MPR), curved planar reformation(CPR), volume rendering technique(VRT), maximum intensity projection(MIP), visual endoscopy(VE). Result: Fifty-two cases were suffered from aortic atherosclerosis(including 5 aortic aneurysm, 7 aortic dissection), 4 were only suffered from calcification of aortic wall and 7 were normal. Conclusions: Multi-slice spiral CT angiography of aorta is accurate and non-invasive for diagnosing aortic atherosclerosis, aortic dissection and aortic aneurysm, and it can be a preferred method for the aortic diseases.
