The Preliminary Study of Real-time Ultrasound Elastography in Evaluating of Carotid Atherosclerotic Plaque Stability
摘要
Abstract
Objective To explore the application value of the real-time ultrasound elastography in evaluating of carotid atherosclerotic plaque stability. Methods 41 patients of atherosclerosis with 65 common carotid artery plaques were examined with the real-time ultrasound elastography, and the plaque of different two-dimensional gray scale image features and the corresponding elastic scoring and elastic strain ratio were analyzed. Results (1) Two-dimensional gray-scale ultrasound found 65 plaques, including 35 hypoechoic plaques, 3 hybrid echo plaques and 7 hyperechoic plaques. (2) Hypoechoic plaque elasticity scores were mostly 1 points; the hybrid echo plaque ones were mostly 2-3 points; hyperechoic plaque ones were more than 4 points. Three groups had statistically significant differences in plaque elasticity score (P< 0.05). (3) Strain rate of hyperechoic plaque group and hybrid echo plaques group plaque was significantly higher than hypoechoic plaque group, the difference was statistically significant (P<0.05) ; Strain rate of hyperechoic plaque group were significantly higher than hypoechoic plaque group, the difference was statistically significant (P <0.05). (4) There was a good correlation between two-dimensional ultrasound plaque characteristics and the elasticity score and elastic strain ratio. Conclusion Real-time ultrasound elastography by visual score and strain rate ratio (B/A ratio, the hardness ratio) can reflect the acoustic characteristics of the plaque, and provide more information for the assessment of atherosclerotic plaque stability .关键词
