Deep venous thrombosis and pulmonary embolism are the two aspects of venous thrombo-embolism. Investigation of lower limb veins has been part of various diagnostic algorithms in the past 15 years. Recently, the combination of CT venography (CTV) of lower limbs and abdominal veins together with CT angiography of the pulmonary arteries has allowed a complete examination of venous thrombo-embolism in one session. The technical aspects, imaging findings, venous anatomy on CT, interpretative pitfalls, results and advantages of CT venography are reviewed.
深静脉血栓形成和肺栓塞是静脉血栓栓塞的两个方面。在过去15年中，下肢静脉检查一直是各种诊断算法的一部分。最近，下肢和腹部静脉的CT静脉造影（CTV）与肺动脉CT血管造影相结合，使得在一次检查中就能对静脉血栓栓塞进行全面检查。本文对CT静脉造影的技术方面、影像学表现、CT上的静脉解剖、解读陷阱、结果及优势进行了综述。
