Application Value of 16-slice Spiral CT Angiography in Lower Extremity Arterial Disease / 医疗卫生装备

ABSTRACT

Objective To discuss the application value of 16-slice spiral CT in lower extremity angiography diagnosis of arteriosclerotic occlusive disease.Methods The 16-slice spiral CT was performed for 30 patients with disease of lower extremity to reconstruct maximal intensity projection(MIP),volume rendering technique(VR) and curved planar reconstruction(CPR).Results All the examinations of CTA were successful,abdominal aortic stenosis was 4 cases,Iliac artery stenosis was 6 cases,femoral artery stenosis was 8 cases and occlusion was 3 cases;lower leg arterial stenosis was 7 cases and occlusion was 2 cases.There are varying degrees of stenosis or occlusion in following femoral artery for all patients.Conclusion The 16-slice CT of lower extremity angiography can be an intuitive understanding of the extent and scope of lesions,and is a safe,accurate,non-invasive screening method in lower extremity artery.
