Fluids Alter Elasticity Measurements: Porous Wave Propagation Accounts for Shear Wave Dispersion in Elastography

Frontiers in Physics, 2021
In shear wave elastography, rotational wave speeds are converted to elasticity measures using elastodynamic theory. The method has a wide range of applications and is the gold standard for non-invasive liver fibrosis detection.

Propagator and wave-equation inversion for near-receiver material properties [PDF]

, 2004
Near-receiver material properties are required for the separation of the recorded wavefield into upgoing and downgoing P and S waves, and are also important for static time-shift corrections.

How to perform shear wave elastography. Part I [PDF]

, 2021
We recently introduced a series of papers describing how to do certain techniques. This article is the first part of a review of shear wave elastography (SWE). It reports the principles and interpretation of the technique and describes how to optimize it.

Ten Minutes of Passive Hip and Knee Joint Movement Reduces Stiffness Due to Osgood‐Schlatter Disease in the Rectus Femoris Muscle

Arthroscopy, Sports Medicine, and Rehabilitation, EarlyView.
Purpose To investigate the acute effects of passive movement on rectus femoris (RF) stiffness, flexibility, and subjective knee joint pain in patients with Osgood‐Schlatter disease (OSD). Methods Patients with bilateral OSD at the orthopedic clinic between July 2023 and June 2025 were prospectively enrolled.

Limitations and artifacts in shear-wave elastography of the liver [PDF]

Biomedical Engineering Letters, 2017
Recent studies have shown that real-time, two-dimensional shear-wave elastography (2D-SWE) can monitor liver fibrosis by measuring tissue elasticity (i.e., elastic modulus). Two clinical studies of 2D-SWE in the liver have shown that there are several practical issues that can compromise quantitation of liver tissue elasticity. Both general ultrasound (
