ABSTRACT
Objective To evaluate the clinical value of 16-slice spiral CTA for the diagnosis of lower extremity arterial disease.Methods A total of 103 patients with arterial disease at the lower extremities were submitted to 16-slice spiral CTA.A scanner with a slice thickness of 5 mm,pitch 1.15 mm,increment 1.0 mm,and overlapping 30% was used.Totally 90-100 ml of contrast agent was injected at a rate of 3 ml/s.The scanning was started with a Smartprep auto-trigger and persisted for 20-30 s.The reconstructed images were reformed by means of maximum intensity projection,volume rendering technique,and multiplanar reformation.Results The reconstructed images of the 103 cases were clearly demonstrated by CTA,which showed arteriosclerotic occlusion in 64 patients,arteriostenosis in 32,aneurysm in 4,and normal vessels in 3.Among the 103 patients,40 received surgical treatment,which confirmed the results of CTA.Conclusion Lesions in the lower extremity arteries can be well demonstrated by 16-slice spiral CTA,which can serve as a pre-surgery screening and evaluation.
