Elasticity Characteristics of Thenar Muscles in Carpal Tunnel Syndrome.
Ultrasound Med Biol
January 2025
Department of Orthopedic Surgery, Mayo Clinic, Rochester, MN, USA. Electronic address:
Objective: Measurement of thenar muscle elasticity by ultrasound shear wave elastography (SWE) may be useful for the diagnosis and evaluation of carpal tunnel syndrome (CTS), but there is a paucity of information on SWE of the thenar muscles in patients with CTS. The purpose of this study was to investigate the elasticity of the thenar muscles in patients with CTS.
Methods: Twenty-two adult patients with a referral diagnosis of CTS (27 hands) and 20 healthy volunteers as a control (20 dominant hands) participated in this study.

Alzheimers Dement
December 2024
University of Washington, Seattle, WA, USA.
Background: Leveraging non-invasive ultra-high field, 7 Tesla (7T) MRI, with increased signal-to-noise ratio and improved soft tissue contrast afforded by 7T allows us to accurately map tissue microstructure. We aim to use 7T MR Elastography (MRE), 7T Diffusion Tensor Imaging (DTI), 3T amyloid-PET, and Preclinical Alzheimer Cognitive Composite (PACC) score to determine the relationships between these metrics in a cohort of older individuals with either normal cognition (CN), mild cognitive impairment (MCI), or Alzheimer's Disease (AD).
Methods: 7T MRE, 7T DTI, 3T PET (Fig.
Evaluation of ovarian stiffness and its biological mechanism using shear wave elastography in polycystic ovary syndrome.
Sci Rep
January 2025
Department of Ultrasound, The Second Affiliated Hospital of Fujian Medical University, No. 34 North Zhongshan Road, Quanzhou, 362000, Fujian Province, China.
Article Synopsis
- Polycystic ovary syndrome (PCOS) is a common endocrine disorder characterized by various factors, and this study utilizes a noninvasive imaging technique called shear wave elastography (SWE) to assess ovarian stiffness in patients with PCOS.
- The research found that individuals with PCOS had significantly higher numbers of follicles, ovarian volume, and increased SWE measurements compared to healthy controls, identifying these factors as independent risk indicators for PCOS.
- Additionally, a rat model showed that increased ovarian stiffness was linked to fibrosis and changes in gene expression related to the ovarian structure, suggesting a biological connection between stiffness and the prevalence of PCOS.
Artificial Intelligence in Diagnostic Breast Ultrasound: A Comparative Analysis of Decision Support Among Radiologists With Various Levels of Expertise.
Eur J Breast Health
January 2025
Department of Biomedical Engineering, Yeditepe University Faculty of Engineering, İstanbul, Turkey.
Objective: To investigate integrating an artificial intelligence (AI) system into diagnostic breast ultrasound (US) for improved performance.
Materials And Methods: Seventy suspicious breast mass lesions (53 malignant and 17 benign) from seventy women who underwent diagnostic breast US complemented with shear wave elastography, US-guided core needle biopsy and verified histopathology were enrolled. Two radiologists, one with 15 years of experience and the other with one year of experience, evaluated the images for breast imaging-reporting and data system (BI-RADS) scoring.

Med Acupunct
October 2024
Department of Health Sciences, Kansai University of Health Sciences, Kumatori, Osaka, Japan.
Objective: This study investigated the effects of electroacupuncture (EA) on muscle hardness changes induced by exercise, using ultrasound real-time tissue elastography (RTE).
Materials And Methods: Healthy men were included in 2 experiments. Experiment 1 had 11, and Experiment 2 had 10.
