目的：探讨64层螺旋CT对下肢动脉疾病的评估价值以及64层螺旋CT两种不同扫描方法对下肢动脉显示效果的对照研究。方法41例临床有不同程度症状且初诊疑为下肢动脉疾病的患者，分为两组，19例患者行自动触发扫描，22例患者行手动触发扫描，行64层螺旋CT扫描，根据检查结果判断64层螺旋CT对下肢动脉的评估价值，其根据对下肢动脉的显示效果分别评估后进行对照研究。结果41例患者中38例能显示腹主动脉下段至胫腓动脉全程；19例行自动触发扫描的患者中12例图像质量佳且血管显示清晰，5例部分下肢动脉图像质量欠佳且管壁模糊，2例图像部分下肢动脉图像质量差且无诊断价值；22例行手动触发扫描的患者中5例图像质量佳且血管显示清晰，5例部分下肢动脉图像质量欠佳且管壁模糊，1例图像部分下肢动脉管腔内狭窄程度无法诊断，1例部分下肢动脉节段图像质量差且无诊断价值。结论手动触发扫描对腘动脉远侧下肢动脉显示效果优于自动触发扫描，且64层螺旋CT下肢动脉造影对下肢动脉疾病的诊断具有较好的评估价值。

Objective To discuss the evaluation value of 64 slice spiral CT detecting of lower extremity arteriosclerosis obliterans and compare the effect of two different CT scan methods.Methods 41 patients with different symptoms and firstly diagnosed as lower extremity arteriosclerosis obliterans were divided into two groups.19 patients underwent auto bolus triggering method compared with 22 patients underwent manual bolus triggering method. And the results of the display of lower extremity artery were evaluated within the two groups.Results The images of 38 among 41 patients can show a throughout panorama from the abdominal aorta to the tibia peroneal artery; 5 of the 19 patients underwent auto bolus triggering method got poorer images of the lower extremity artery, and 2 patients among the 5 who got poorer images were distal popliteal artery.5 of the 22 patients underwent manual bolus triggering method got poorer images atproximal popliteal artery.Conclusion The manual bolus triggering method is better than auto bolus triggering method, and lower limb angiography of 64 spiral CT in the diagnosis of lower extremity artery disease is of great value assessment.
