Shear wave elastography in MSK [PDF]

Ultrasound in Medicine & Biology, 2019
Objectives To describe our experience applying shear wave elastography to the musculoskeletal system, as well as some potential sources of artifact when applying this new technology. Summary Disease states in the musculoskeletal system often manifest as altered tissue morphology evident on conventional gray-scale ultrasound imaging.

What Are the Limitations of Measuring Bladder Compliance, As the Sole Indicator of Future Risk to the Upper Urinary Tract and Renal Function? ICI‐RS 2025

Neurourology and Urodynamics, EarlyView.
ABSTRACT Introduction Maintenance of bladder filling and urinary storage at low intravesical pressures is fundamental to minimizing risk to the upper urinary tract. Bladder compliance describes the relationship between the bladder volume and the change in detrusor pressure during the filling phase of urodynamics.

Diagnostic value of two dimensional shear wave elastography combined with texture analysis in early liver fibrosis. [PDF]

, 2019
BACKGROUND: Staging diagnosis of liver fibrosis is a prerequisite for timely diagnosis and therapy in patients with chronic hepatitis B. In recent years, ultrasound elastography has become an important method for clinical noninvasive assessment of liver ...

Multifrequency Multiparameter Magnetic Resonance Elastography Applied to an In Vivo Porcine Model for Assessing Portal Hypertension

Portal Hypertension &Cirrhosis, EarlyView.
Portal hypertension, a critical complication in chronic liver disease, has long relied on invasive hepatic venous pressure gradient measurement for definitive diagnosis. This study establishes that multifrequency three‐dimensional magnetic resonance elastography (3D‐MRE) can noninvasively quantify portal pressure, with splenic stiffness and loss ...

Elastographic presentation of medullary thyroid carcinoma [PDF]

, 2013
Aim of the study was to evaluate the elastographic appearance of medullary thyroid carcinoma (MTC) by a retrospective evaluation of 18 nodules histologically proven as MTC. Free-hand qualitative elastography was performed using Hitachi Logos EUB 7500.

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.

Liver Fibrosis Tests and Outcomes of Bariatric Surgery in Morbidly Obese Patients With MASLD

Portal Hypertension &Cirrhosis, EarlyView.
This study validates commonly used non‐invasive tests for liver fibrosis in morbidly obese patients with biopsy‐proven MASLD and evaluates outcomes after bariatric surgery. These non‐invasive tests show low diagnostic accuracy for baseline liver fibrosis, while bariatric surgery significantly improves liver stiffness, metabolic profiles, and ...

Fast Quantitative Evaluation of the Amelioration Effect in MASLD During Semaglutide Treatment Using Ultrasound‐Derived Fat Fraction and Fat‐to‐Muscle Ratio

Portal Hypertension &Cirrhosis, EarlyView.
Metabolic dysfunction‐associated steatotic liver disease (MASLD) is a chronic liver disease. Research into a feasible, rapid, and effective assessment method is crucial for evaluating the therapeutic effects of semaglutide in MASLD. This prospective study utilized ultrasound‐derived fat fraction measurement and fat‐to‐muscle ratio to evaluate hepatic ...

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 ...

Improved shear wave-front reconstruction method by aligning imaging beam angles with shear-wave polarization: Applied for shear compounding application [PDF]

, 2016
In shear compounding, shear waves are generated at various angles and individual elasticity maps are averaged to reduce noise and improve accuracy. The steered shear waves tilt the tissue motion direction therefore conventional plane wave tracking is not
