Wall shear stress (WSS) is an important contributor to vessel wall remodeling and
atherosclerosis. However, image-based WSS estimation from 4D Flow MRI underestimates …

This study introduces a novel wall shear stress (WSS) estimation method for 4D flow MRI.
The method improves the WSS accuracy by using the reconstructed pressure gradient and …

Abstract Wall Shear Stress (WSS) has been demonstrated to be a biomarker of the
development of atherosclerosis. In vivo assessment of WSS is still challenging, but 4D Flow …

Background Wall shear stress (WSS) presents an important parameter for assessing blood
flow characteristics and evaluating flow‐mediated lesions in the aorta. Purpose To …

Computational fluid dynamics (CFD) is a valuable tool for personalised, non-invasive
evaluation of hemodynamics in arteries, but its complexity and time-consuming nature …

Several 2D methods have been proposed to estimate WSS and OSI from PC-MRI,
neglecting the longitudinal velocity gradients that typically arise in cardiovascular flow …

Abstract Objective Three-dimensional (3D) time-resolved phase-contrast cardiac magnetic
resonance (4D flow CMR) allows for unparalleled quantification of blood velocity. Despite …

In the last few years, wall shear stress (WSS) has arisen as a new diagnostic indicator in
patients with arterial disease. There is a substantial evidence that the WSS plays a …

Purpose To develop a rapid segmentation‐free method to visualize and compute wall shear
stress (WSS) throughout the aorta using 4D Flow MRI data. WSS is the drag force‐per‐area …

With the global rise of cardiovascular disease including atherosclerosis, there is a high
demand for accurate diagnostic tools that can be used during a short consultation. In view of …
