Abstract
Objective:To investigate the effects of static ultrasound elastography on the elastic modulus of normal breast tissue.Methods: (1)Fifteen cases of normal breasts was tested by static ultrasound elastography at the same locations. Intercepted two pictures each time with one stress-free and the other compressed the maximum amount. For these two cases we measured the breast thickness and calculated the minimum stretch ratios(λ). (2)Fifty breasts with no breast nodules were prospectively enrolled in the study. Intercepted two pictures each time with one stress-free and the other compressed to the minimum stretch ratios(λ). For these two cases we measured the Elastic modulus (E0, Em, kPa). Calculate the elastic modulus change ratio (Rm/0).Results: (1)The minimum stretch ratio caused by static ultrasound elastography was 0.74±0.07. (2)The elastic modulus change ratio of static ultrasound elastography was 4.38±1.72. Conclusion: The normal operation of static ultrasound elastography caused 74 percent deformation in normal breast tissue. There was 4.38 times elastic modular increasing caused by 74 percent deformation in normal breast tissue.关键词
