Abstract:
Objective To evaluate the diagnostic value of shear wave elastography on deep venous thrombosis in different stage.Methods Models of rabbits'deep venous thrombosis have been established to noninvasively measure Young's moduli of thrombosis in day 1 ,4,7,10 and 14 respectively by shear wave elastography.Results The elastic modulus of thrombosis increased with increment of the stages of thrombosis.Specifically,the mean Young's moduli of thrombosis increased from (4.0±1 .42)kPa (day 1)to (25.71 ±6.09)kPa (day 14),with statistical differences between each two observation time points (P <0.05).Conclusions Shear wave elastography can effectively reflect the elasticity of thrombosis in different stages,and the stage of thrombosis can be estimated judging by quantitative ultrasound elasticity preliminarily.
