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.
