Reference Values for Shear Wave Elastography of Neck and Shoulder Muscles in Healthy Individuals

Ultrasound International Open, 2018
Purpose to establish reference values for ultrasound shear-wave elastography for pericranial muscles in healthy individuals (m. trapezius, m. splenius capitis, m. semispinalis capitis, m. sternocleidomastoideus and m. masseter).

Value of 2‐Dimensional Shear‐Wave Elastography in Assessing Tibial Nerve Stiffness in Diabetic Peripheral Neuropathy

Journal of Ultrasound in Medicine, EarlyView.
Objectives The morphological alterations of the tibial nerve in patients with diabetes mellitus, both with and without diabetic peripheral neuropathy (DPN), are challenging to differentiate using B‐mode ultrasound. In this study, we assessed the stiffness changes of the tibial nerve by 2‐dimensional shear‐wave elastography (2D‐SWE). Methods We gathered

Wearable bioadhesive ultrasound shear wave elastography

Science Advances
Acute liver failure (ALF) is a critical medical condition defined as the rapid development of hepatic dysfunction. Conventional ultrasound elastography cannot continuously monitor liver stiffness over the course of rapidly changing diseases for early detection due to the requirement of a handheld probe.

Shear Wave Elastography for Characterization of Breast Lesions in Clinical Routine

Journal of Ultrasound in Medicine, EarlyView.
Objectives Breast cancer remains a major global health challenge, and conventional B‐mode ultrasound frequently encounters limitations in reliably distinguishing benign from malignant lesions, particularly within intermediate Breast Imaging‐Reporting and Data System (BI‐RADS) categories.

Shear waves in prestrained poroelastic media [PDF]

, 2017
Shear wave elastography measures shear wave speed in soft tissues for diagnostic purposes. In [1], shear wave speed was shown to depend on prestrain, but not necessarily prestress, in a perfused canine liver.

Exploration of a Multimodal Machine Learning Model Integrating Ultrasound and Clinical Indicators for the Diagnosis of Diabetic Peripheral Neuropathy

Journal of Ultrasound in Medicine, EarlyView.
Objectives Based on ultrasound technology and clinical indicators, this study intends to develop multiple risk prediction models for diabetic peripheral neuropathy (DPN), conduct comparative analyses of these models, and further evaluate and validate the diagnostic efficacy of the optimal model for DPN as well as its potential in clinical application ...

Ultrasound Elastography: Review of Techniques, Clinical Application, Technical Limitations, and Safety Considerations in Neonatology

Acta Medica Martiniana, 2020
Ultrasound elastography is a relatively new non-invasive diagnostic imaging technology that maps elastic properties and the stiffness of soft tissue. In general, these methods can be classified into strain imaging methods that use internal or external ...

Radiative transfer and diffusion limits for wave field correlations in locally shifted random media

, 2013
The aim of this paper is to develop a mathematical framework for opto-elastography. In opto-elastography, a mechanical perturbation of the medium produces a decorrelation of optical speckle patterns due to the displacements of optical scatterers.

Single‐Breathhold 3D MR Elastography in the Liver, With Simultaneous R2* and PDFF Mapping

Magnetic Resonance in Medicine, EarlyView.
Purpose To develop a sequence for the rapid acquisition of MR elastography (MRE) parameters in 3D, with simultaneous measurement of proton‐density fat fraction (PDFF) and R2* for multiparametric assessment of liver disease. Methods The proposed sequence uses an interleaved motion‐encoding scheme to acquire 3D volumes of all motion encodings and wave ...
