Abstract

Introduction: The aim of the study is to evaluate the ability of Real Time Elastography (RTE) to assess the stiffness of carotid plaque in patients.

Materials and methods: 96 patients with carotid plaque were enrolled in this study. hypo-echo plaques, complex-echo plaques and strong-echo plaques in 96 patients were found by gray scale ultrasound. Meanwhile, RTE was used to display a color-coded strain map and calculate the strain ratio of different types of echo plaques with surrounding tissue.

Results: Color-coded RTE image showed that the hypo-echo plaques were mainly red or green, complex-echo plaques were blue and green, and the strong-echo plaques were blue and white. The mean strain ratio of hypo-echo plaques, compounded-echo plaques and strong-echo plaques were1.21±0.69, 4.35±3.19 and 41.14±33.09, respectively. There was statistic difference (P<0.05).

Conclusion: The strain ratio of hypo-echo plaques, complex-echo plaques, strong-echo plaques increased in turn. RTE combi- ned conventional ultrasound to provide more information in the diagnosis of carotid artery plaque stability.
