目的探讨64排128层螺旋容积CT(VCT)成像技术在双下肢动脉血管造影术中的应用价值.方法对60例患者进行下肢多层螺旋CT血管造影检查,平扫后静脉团注对比剂进行CT血管造影,图像采用最大密度投影、曲面重建、容积再现技术等后处理技术重建血管,观察病变血管显示情况.结果 60例患者经VCT血管重建成像均能清晰下肢动脉病血管不规则钙化、扭曲、囊袋样扩张、管壁僵硬、迂曲等,能清晰显示术后金属支架及人工血管全貌.VCT扫描时间为22 s、25 s、28 s,扫描间隔时间3s,通过后处理软件,均能显示下肢动脉及主要分支,使下肢动脉能完整显示,无任何骨骼干扰,完全符合临床诊断.结论 64排128层螺旋VCT血管成像技术能清晰地显示下肢动脉及其病变,可以作为下肢动脉疾病术前评价和筛选的主要方法.

Objective To explore the application value of VCT 64-row with 128-layer spiral extremities arterial imaging techniques and methods in the double lower limb artery.Methods 60 patients on lower limbs MSCTA angiography after Saul,flat on intravenous regiment note contrast agents CT angiography,image the maximum intensity projection(MIP),curved planner reconstruction(CPR),volume rendering(VR)after-treatment technology reconstructed vessels.Results All 60 patients showed the lower limb arterial and main branch.Conclusion 64-row helical VCT angiographic with 128-layer could clearly show that lower limb artery and pathological changes,and become main methods of preoperative evaluation and selection for the lower limb artery disease.
