Until recently, phlebography with contrast agents has been the standard method for demonstration of deep venous thrombosis in the lower limb (DVT). In recent years, however, this has been replaced to an increasing extent by ultrasonic scanning. In contrast to radiographic examination, this method does not require injection of a contrast agent and it does not employ ionizing irradiation. The principle of ultrasonic scanning is that a normal vein may be compressed flat by means of slight pressure from the transducer whereas a vein filled with thrombi cannot be compressed. Ultrasonic examination is not (yet?) of diagnostic value in the leg but, more centrally, it is of the same diagnostic value as radiographic examination. It is suggested that ultrasonic scanning can replace phlebography in patients with their first DVT. If this gives a negative result, it may possibly be supplemented by phlebography of the veins of the leg.
直到最近，使用造影剂的静脉造影术一直是显示下肢深静脉血栓形成（DVT）的标准方法。然而，近年来，这种方法越来越多地被超声扫描所取代。与放射学检查不同，这种方法不需要注射造影剂，也不使用电离辐射。超声扫描的原理是，正常静脉可通过换能器施加的轻微压力被压瘪，而充满血栓的静脉则不能被压瘪。超声检查对腿部尚无（或尚未？）诊断价值，但在更靠近中心的部位，其诊断价值与放射学检查相同。有人认为，超声扫描可取代首次发生DVT患者的静脉造影术。如果超声扫描结果为阴性，可能需要对腿部静脉进行静脉造影术作为补充。
