Methods 63 patients underwent 双源CT双向法静脉 CTV checks.In the bidirectional CTV, contrast agent was injected via the left cubital vein and dorsal venous, respectively, scanning was started after 2.5 minutes of the beginning 造影在下肢深静脉 of injection. In indirect CTV the contrast agent was injected through the cubital vein, the scan was started after 2.5 minutes of the beginning of injection. In the direct CTV, 血栓中的初步应用 60ml diluted contrast agent was injected via the diseased dorsal vein, the rate 1.5ml/ s, scanning started after 1 minutes of the beginning of injection.Ddual-energy scanning protocol was uniformly applied with the voltage ratio 0.5 of 100kV and Sn140kV, 1.江苏省中医院医学影像科 CareDose4D automatically tracking total of 108 lower limbs and 324 vascular segments
