Abstract

Background: Wall shear stress (WSS) plays an indispensable role in shaping the trajectory of vascular diseases such as atherosclerosis and aneurysms. Specific patterns of low and oscillating WSS are implicated in the promotion of plaque accumulation, whereas elevated WSS levels are associated with inflammatory responses, the synthesis of metalloproteases, and eventual rupture of plaque. Therefore, an accurate, noninvasive quantification of local hemodynamics and WSS is integral to the precise diagnosis of vascular disorders. Ultrasound imaging has emerged as a favored modality for measuring the WSS owing to its noninvasive nature, ease of access, and user-friendly interface. However, existing reviews primarily focus on the assessment of blood flow characteristics, including velocity profiles and volume flow rates. To the best of our knowledge, thus far, no review has been dedicated to ultrasound imaging techniques for the measurement of in vivo WSS.

Purpose: This study aimed to perform a thorough overview of current and emerging ultrasound imaging methodologies tailored for in vivo WSS quantification.

Basic procedure: The fundamental principles of WSS measurements were explored, and various techniques—-Doppler ultrasound imaging, ultrasound imaging velocimetry, and speckle decorrelation—-that are employed for WSS assessment were studied.

Main findings: These techniques show promise for clinical applications by facilitating noninvasive and accurate WSS measurements of vital parameters concerning vascular physiology. Further investigations are warranted to overcome specific challenges, such as the accurate detection of vascular wall boundaries.

Conclusions: The findings of this review are anticipated to contribute to advancements in ultrasound imaging techniques for in vivo WSS measurements.

墙剪应力测量的超声成像
背景:壁剪切应力(WSS)在动脉粥样硬化和动脉瘤等血管疾病的发展过程中起着不可或缺的作用。低WSS和振荡WSS的特定模式与促进斑块积累有关,而WSS水平升高与炎症反应、金属蛋白酶的合成和斑块的最终破裂有关。因此,准确、无创地量化局部血流动力学和WSS对于血管疾病的精确诊断是不可或缺的。超声成像由于其无创性、易于获取和用户友好的界面,已成为测量WSS的首选方式。然而,现有的综述主要集中在血流特性的评估上,包括速度分布和体积流速。据我们所知,到目前为止,还没有关于超声成像技术测量体内WSS的综述。目的:本研究旨在对当前和新兴的用于体内WSS量化的超声成像方法进行全面概述。基本程序:探讨了WSS测量的基本原理,并研究了用于WSS评估的各种技术——多普勒超声成像、超声成像测速和散斑去相关。主要发现:这些技术通过促进血管生理学重要参数的无创和准确的WSS测量,显示了临床应用的前景。进一步的研究是必要的,以克服具体的挑战,如准确检测血管壁边界。结论:本综述的发现有望促进超声成像技术在体内WSS测量方面的进步。
