Limited accuracy in the clinical diagnosis of deep vein thrombosis (VT) makes such diagnostic tests such as duplex sonography or venography necessary. Exact information on the age and extent of the thrombus are necessary for the clinician to optimize the therapeutic management. The correct diagnosis of calf vein thrombosis and of recurrent VT in patients with postphlebitis changes also has implications for treatment. After exclusion of thrombosis, the radiologist should evaluate the leg for other possible causes of symptoms besides VT. Investigation of the venous system also has a role in the diagnosis in patients with suspected pulmonary embolism. In patients with chronic venous insufficiency the deep venous system should be assessed for patency and venous valve function. The superficial veins should be differentiated in segments with sufficient or insufficient venous valves, and it is also necessary to look for insufficiency of the perforating veins. In patients with superficial phlebitis there is risk of propagation into the deep venous system.
深静脉血栓形成（VT）临床诊断的准确性有限，这使得诸如双功超声检查或静脉造影等诊断测试成为必要。对于临床医生优化治疗管理而言，获取有关血栓年龄和范围的确切信息至关重要。小腿静脉血栓形成以及静脉炎后改变患者复发性VT的正确诊断对治疗也具有重要意义。排除血栓形成后，放射科医生应评估腿部除VT外其他可能的症状原因。静脉系统检查在疑似肺栓塞患者的诊断中也发挥着作用。对于慢性静脉功能不全患者，应评估深静脉系统的通畅情况和静脉瓣膜功能。应区分浅静脉瓣膜功能充足或不足的节段，还需要查找穿通静脉功能不全。对于浅表性静脉炎患者，存在血栓蔓延至深静脉系统的风险。
