title: Role of real-time elastography in assessing the stage of thrombus.
abstract: Due to major complication that acute thrombosis can occur, we aim to observe the value of real-time tissue elastography (RTE) in assessing the stage of thrombi.
  
  
  
  We prospectively analyzed 132 patients with deep venous thrombosis confirmed by clinical symptoms and conventional ultrasound examination. RTE imaging of thrombosis were estimated according Itoh's 5-point scale and we also calculated the strain ratio (reference/clot ratio).
  
  
  
  Differences in thrombus displacement have been presented as different color maps. In the group of acute thrombosis, 70.9% (39/55) showed red color. In the group of subacute thrombosis, 62.8% (27/43) showed green color. In the group of chronic thrombosis, 67.6% (23/34) showed blue color. The strain ratio of the chronic thrombosis group and the subacute thrombosis group were higher than that of the acute thrombosis group (P<0.001, P<0.05). The strain ratio of the chronic thrombosis group was higher than that of the acute and subacute thrombosis group (P<0.05).
  
  
  
  RTE has good diagnostic value for assessing the stage of thrombi.
