Abstract

Our objective was to assess strain in common carotid artery (CCA) plaques using a previously validated speckle tracking algorithm. Radial and longitudinal strain was measured in 7 patients (77 ± 6 years) with carotid atherosclerosis and was compared with a quantitative visual assessment grading of plaques on the Gray-Weale scale by two experienced physicians. A greater pulse-pressure adjusted radial and longitudinal strain was found in echolucent plaques compared to echogenic plaques. This study shows the feasibility of ultrasound speckle tracking strain estimation in plaques and indicates the possibility to characterize plaques using speckle tracking strain in vivo.
基于超声斑点跟踪的体内颈动脉径向和纵向斑块应变估计
我们的目的是使用先前验证的斑点跟踪算法评估颈总动脉(CCA)斑块的应变。对7例颈动脉粥样硬化患者(77±6岁)的径向和纵向应变进行测量,并与两名经验丰富的医生对斑块进行灰色-威尔分级的定量视觉评估进行比较。与回声斑块相比,在超声斑块中发现了更大的脉压调整的径向和纵向应变。本研究表明了超声斑点跟踪应变估计在斑块中的可行性,并指出了利用斑点跟踪应变在体内表征斑块的可能性。
