Chronic Liver Disease: Assessing Inflammation and Fibrosis Using Three‐Dimensional MR Elastography With Same‐Day Biopsy in a Prospective Cohort

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Three‐dimensional (3D) MR elastography (MRE) derives viscoelastic parameters that may reflect inflammation, but their frequency dependence and the influence of steatosis on inflammation grading and fibrosis staging remain unclear. Purpose To investigate 3D multifrequency MRE for assessing hepatic inflammation, fibrosis stage across ...

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.

Liver disease in Shwachman‐Diamond syndrome: A comprehensive characterization across the age spectrum

Journal of Pediatric Gastroenterology and Nutrition, EarlyView.
Abstract Objectives Shwachman‐Diamond syndrome (SDS) is an inherited bone marrow failure disorder, and its hepatic phenotype is poorly defined. Our objective was to systematically characterize the prevalence, features, and outcomes of liver injury in a multicenter SDS cohort. Methods Retrospective registry study of 171 patients with biallelic Shwachman‐

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.

Intervertebral disc characterization by shear wave elastography: an in-vitro preliminary study [PDF]

, 2014
Patient-specific numerical simulation of the spine is a useful tool both in clinic and research. While geometrical personalization of the spine is no more an issue, thanks to recent technological advances, non-invasive personalization of soft tissue’s ...

Liver stiffness in patients with Shwachman‐Diamond syndrome

JPGN Reports, EarlyView.
Abstract Objective This case series aims to describe whether transient elastography (TE) as a marker of liver stiffness is associated with clinically important liver disease in children and young adults with Shwachman‐Diamond Syndrome (SDS). Methods All patients ≤25 years of age with genetically confirmed SDS seen in the Pediatric Gastroenterology ...

Spatial resolution in dynamic optical coherence elastography [PDF]

, 2019
Dynamic optical coherence elastography (OCE) tracks elastic wave propagation speed within tissue, enabling quantitative three-dimensional imaging of the elastic modulus. We show that propagating mechanical waves are mode converted at interfaces, creating

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.

Successful treatment of vertically acquired Hepatitis C in a child using direct‐acting antiviral therapy administered via gastrojejunal tube: A case report

JPGN Reports, EarlyView.
Abstract Hepatitis C virus (HCV) remains a significant global health burden, with vertical transmission being the primary route of infection in children. Direct‐acting antivirals (DAAs) have transformed HCV treatment in pediatrics, but limited data exist on their administration in medically complex children who are dependent on enteral tubes. We report

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 ...
