Application Value of 16-slice Spiral CT for Diagnosis of Aortic Aneurysms

Objective To evaluate the efficacy of 16-slice Spiral CT angiography(CTA) with post-processing techniques in the diagnosis of aortic aneurysms.Methods A total of 30 patients with aortic aneurysms confirmed by surgery or DSA were recruited.Patients' images of 16-slice Spiral CT scanning CTA were retrospectively analyzed.All original images data were dealt with adw4.2 workstation.Reconstruction was performed in several ways,that is,by shaded volume reconstruction(SVR),multi-planar reconstructions(MPR),maximum intensity reformation(MIP),and curved planar reformation(CPR),and CT virtual endoscopy(CTVE).Results There were 2 cases of ascending aortic aneurysm,7 cases of descending aortic aneurysm,9 cases of abdominal aortic aneurysm and 12 cases of artery pseudo aneurysm including 4 ones of ascending artery pseudo aneurysm,4 ones of descending artery pseudo aneurysm and 4 ones of abdominal artery pseudo aneurysm.Conclusion 16-slice Spiral CT can show anatomy change of aortic aneurysms exactly,rapidly and non-invasively,and thus is important for treatment scheme establishment,post-operation observation and follow up.
