Diagnostic Performance of Ultrasound to Evaluate Mild Hip Osteoarthritis: Comparison With Radiography and MRI

Journal of Clinical Ultrasound, EarlyView.
A moderate‐sized femoral neck osteophyte (white arrow) in US (A), anteroposterior CR (B), and MRI (C). Additional osteoarthritis‐related changes (arrowheads) are visible in CR and MR, but not in US. US and CR demonstrated similar moderate diagnostic capability to detect mild hip osteoarthritis and were associated with increased hip pain.

Application of Multimodal Ultrasound Combined With BI‐RADS in Classification and Diagnosis of Non‐Mass Breast Lesions

Journal of Clinical Ultrasound, EarlyView.
This study demonstrates that integrating microvascular flow imaging, shear wave elastography, and contrast‐enhanced ultrasound with the BI‐RADS classification significantly improves the diagnostic accuracy for non‐mass breast lesions, offering a more reliable tool for differentiating benign from malignant findings.

Strain Elastography - How To Do It?

Ultrasound International Open, 2017
Tissue stiffness assessed by palpation for diagnosing pathology has been used for thousands of years. Ultrasound elastography has been developed more recently to display similar information on tissue stiffness as an image.

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.

Prospective Comparison of DWI‐Derived Virtual MR Elastography and Conventional MR Elastography in Metabolic Dysfunction‐Associated Steatotic Liver Disease and Healthy Volunteers

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Virtual MR elastography (VMRE) and MRE have been proposed for liver fibrosis staging in metabolic dysfunction‐associated steatotic liver disease (MASLD), but VMRE's diagnostic performance remains debated. Purpose To assess the inter‐visit and inter‐reader reproducibility of fat‐uncorrected and fat‐corrected diffusion‐weighted ...

Motion Mitigation Techniques for Abdominal and Cardiac MR Imaging

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT MRI of the heart and abdominal organs provides unparalleled soft tissue contrast and quantitative biomarkers, yet remains highly susceptible to physiological motion. Contractions of the myocardium, respiratory excursions, peristalsis, vascular pulsatility, and unpredictable bulk patient movement generate artifacts that impair image quality ...

Vibration‐controlled transient elastography in pediatric metabolic dysfunction‐associated steatotic liver disease

Journal of Pediatric Gastroenterology and Nutrition, EarlyView.
Abstract Objectives Metabolic dysfunction‐associated steatotic liver disease (MASLD) is a prevalent disease in children. Vibration‐controlled transient elastography (VCTE) offers a noninvasive alternative to liver biopsy, using controlled attenuation parameter (CAP) to estimate steatosis and liver stiffness measurement (LSM) for fibrosis.

Comparison of strain and shear wave elastography for qualitative and quantitative assessment of breast masses in the same population

Scientific Reports, 2018
We investigated addition of strain and shear wave elastography to conventional ultrasonography for the qualitative and quantitative assessment of breast masses; cut-off points were determined for strain ratio, elasticity ratio, and visual score for ...

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).
