Objective    To evaluate the value of 16-slice spiral computed tomography (SCT) and its three-dimensional reconstruction in diagnosis of aortic aneurysms (AA).     Methods    Thirty-two patients with AA underwent unenhanced and contrast-enhanced spiral CT with a 16-slice scanner and their images were processed into three-dimensional reconstructions. Among the 32 patients

29 received operation.      Results    The size

calcification and the relation with branch vessels of AA could be clearly shown on CT and CTA images. The size

and the dilatation of ascending aortic root of 26 aneurysms on CT and CTA images were confirmed surgically.     Conclusion    16-slice SCT axial and three-dimensional images can fast

noninvasively and completely reveal the pathological and anatomical features of aortic aneurysms

and provide detailed imaging information for clinical therapy. It’s very important for selecting the treatment strategies

evaluating the curative effect postoperatively and in the follow-up period.
