Evaluation of hepatic steatosis in obese children and adolescents using immune-inflammatory markers and shear wave elastography.
J Ultrason
January 2025
Radiology, Malatya Training and Research Hospital, Malatya, Turkey.
Aim: To investigate the changes in liver stiffness and immune-inflammatory markers associated with obesity and the degree of hepatic steatosis in obese children and adolescents.
Methods: A total of 76 obese children and adolescents aged 6-18 years, with body mass index percentiles >95th, were included in the study. Patients with metabolic syndrome, diabetes mellitus, and chronic liver disease were excluded.

In this article, we comment on the article by Cheng published in recently. Posthepatectomy liver failure (PHLF) remains a leading cause of hepatectomy-related mortality and can be evaluated according to liver reserve function. Liver stiffness (LS) measured by ultrasonic elastography and spleen area demonstrate a strong correlation with hepatic proliferation, fibrosis, and portal vein congestion, thus indirectly reflecting liver reserve function.

J Clin Ultrasound
January 2025
Department of Ultrasonography, The Second Affiliated Hospital of Chongqing Medical University, Chongqing, China.
Purpose: This study evaluates the effectiveness of lacrimal gland ultrasonography (LGUS) and shear wave elastography (SWE) in distinguishing primary Sjögren's syndrome (PSS) patients from healthy controls and examines their role in assessing disease activity and prognosis.
Methods: A total of 35 PSS patients and 23 age- and gender-matched healthy controls were included. LGUS was used to grade lacrimal gland structure, while SWE assessed gland elasticity.
Combining Multifrequency Magnetic Resonance Elastography With Automatic Segmentation to Assess Renal Function in Patients With Chronic Kidney Disease.
J Magn Reson Imaging
January 2025
Department of Radiology, The Fourth Clinical Medical College of Guangzhou University of Chinese Medicine (Shenzhen Traditional Chinese Medicine Hospital), Shenzhen, China.
Background: Multifrequency MR elastography (mMRE) enables noninvasive quantification of renal stiffness in patients with chronic kidney disease (CKD). Manual segmentation of the kidneys on mMRE is time-consuming and prone to increased interobserver variability.
Purpose: To evaluate the performance of mMRE combined with automatic segmentation in assessing CKD severity.
Identifying dehydration-induced shear velocity anomaly in the Earth's core-mantle boundary.

The steep temperature gradient near the bottom of the mantle is known to generate a negative correlation between the shear wave velocity ( ) and the depth in most regions of the D″ layer, as detected by seismological observations. However, increasing with depth is observed at the D″ layer beneath Central America, where the Farallon slab sinks, and the origin of this anomaly has not been well constrained. Here, we calculate the thermoelastic constants and obtain the elastic wave velocities of hydrous phase H with various Al contents and cation configurations, which may act as a water carrier to the D″ layer.
