OBJECTIVE: This study aims to answer whether Acoustic Radiation Force Impulse Imaging (ARFI) can reasonably be employed in initial examination and follow-up during therapy in patients with sialolithiasis, one of the most common non-malignant disorders of the salivary glands. METHODS: Mechanical tissue properties of affected and contralateral healthy salivary glands were analyzed by ARFI in 129 patients with sialolithiasis. In different subgroup analyses, ARFI shear wave velocity values were compared between healthy and diseased submandibular or parotid glands, salivary glands with calculi exhibiting different sizes, as well as before and after therapy...

PURPOSE: Success of ablation treatment depends on the accurate placement of the target ablation focus and the complete destruction of the pathological tissue. Thus, monitoring the formation, location, and size of the ablated lesion is essential. As ablated tissue gets stiffer, an option for ablation monitoring is ultrasound elastography, for imaging the tissue mechanical properties. Reconstruction of elasticity distribution can be achieved by solving an inverse problem from observed displacements, based on a deformable tissue model, commonly discretized by the finite element method (FEM)...

Ultrasound is the preferred initial imaging modality in Europe and Asia for assessing the major salivary glands. In experienced hands, it is sensitive for a range of salivary pathologies, often diagnostic, and also a safe, cost-effective gatekeeper for further investigations as well as image-guided diagnostic biopsies and aspirations. This article reviews the scanning technique and normal sonographic anatomy of major salivary glands and overviews typical sonographic appearances of salivary pathologies, including infective and inflammatory conditions, sialolithiasis, and neoplasms...

BACKGROUND: Placental elasticity may be modified in women with placental insufficiency. Shear wave elastography (SWE) can measure this, using acoustic radiation force, but the safety of its use in pregnant women has not yet been demonstrated. Transient elastography (TE) is a safer alternative, but has not yet been applied to the placenta. Moreover, the dispersion of shear wave speed (SWS) as a function of frequency has received relatively little study for placental tissue, although it might improve the accuracy of biomechanical assessment...

Embolus Analogues (EAs) can provide understanding of the mechanical characteristics of blood clots of cardiac origin. Bovine EAs (n = 29) were fabricated with varying concentrations of thrombin (0-20 NIHU/ml blood). Histological staining confirmed that EA composition compared sufficiently with human samples reported in literature. EAs were mechanically described under seven testing conditions: tensile, compression, shear wave ultrasound elastography (SWE), parallel plate rheometry, indentation, creep and relaxation...

Seyedali Sadeghi, Cassidy Newman, Daniel H Cortes
Long-distance running competitions impose a large amount of mechanical loading and strain leading to muscle edema and delayed onset muscle soreness (DOMS). Damage to various muscle fibers, metabolic impairments and fatigue have been linked to explain how DOMS impairs muscle function. Disruptions of muscle fiber during DOMS exacerbated by exercise have been shown to change muscle mechanical properties. The objective of this study is to quantify changes in mechanical properties of different muscles in the thigh and lower leg as function of running distance and time after competition...
