A Novel Instance Segmentation Method for Real-Time Detection of Thyroid Nodules in Ultrasound Videos: A Multi-Center Study
Thyroid nodules are one of the most common thyroid disorders and can be categorized into benign and malignant thyroid nodules. Currently, the initial diagnosis is made clinically by ultrasonography, and the determination of thyroid nodules is highly dependent on the operating experience and maneuvers of the physician, resulting in fluctuating diagnostic accuracy. Recent studies have shown that using deep learning-based automated diagnostic tools can assist in the segmentation of individual nodules in thyroid ultrasound images. However, in reality, a single frame typically contains multiple nodules.
Review of Techniques and Technologies for Mosaicking Ultrasound Volumes
Ultrasound imaging, known for its affordability, portability and real-time capabilities, has become a crucial diagnostic tool worldwide. However, the limited field of view in 2-D ultrasound and reduced anatomical coverage in current 3-D systems have prompted the development of volumetric compounding. This review aims to outline the techniques and technologies used in mosaicking ultrasound volumes to overcome these challenges and enhance clinical imaging capabilities. This review adheres to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. A search was conducted in four bibliographic databases and grey literature to identify articles that utilised 3-D ultrasound transducers for the registration or compounding of ultrasound volumes. Review selection and characterisation were performed by two independent reviewers. The search identified 72 papers published from 2013 to 2024, with most studies focused on cardiovascular applications (54.2%). The primary goal of these studies was to improve the visualisation of structures (45.8%) and extend the field of view (30.6%). Automation was a significant focus, with 46.6% of studies using automated methods for improved efficiency and accuracy. However, a larger proportion of semi-automated methods indicates that certain tasks still require human intervention. While significant progress has been made in enhancing image quality, future research should focus on refining these methods, exploring under-represented clinical applications, and leveraging state-of-the-art artificial intelligence methods to improve efficiency, accuracy and clinical integration.
Repeated blood-brain barrier opening using low-intensity pulsed ultrasound mitigates amyloid pathology
The delivery of large molecules to the pathological brain is one of the main obstacles in the development of disease-modifying drugs. This is partly due to the presence of the blood-brain barrier (BBB), which blocks the free passage of lipophobic molecules and those larger than 400 Da. One strategy to bypass this natural barrier is to use low-intensity pulsed ultrasound to oscillate circulating micro-sized microbubbles, which then exert mechanical stress on the vessel walls. This procedure allows for temporary disruption of the BBB and enhanced local delivery of therapeutics from the blood to the brain parenchyma. In this study, the effect of repeated BBB opening on neuroinflammation in a healthy mouse model was first explored, followed by the effect of repeated opening on amyloid-beta (Aβ) pathology in an Alzheimer's disease model.
Clinical Application of an AI-Driven Framework for Accurate Endometrial Thickness Measurement in Transvaginal Ultrasound

Evaluating the Clinical Agreement Between Corrected Left Ventricular Ejection Time and Corrected Carotid Flow Time in Coronary Artery Bypass Graft Surgery Patients
Perioperative hemodynamic monitoring plays a crucial role in reducing complications during coronary artery bypass graft (CABG) surgery. Corrected left ventricular ejection time (cLVET) is used to assess cardiac contractility but requires specialized echocardiography expertise. Corrected carotid flow time (ccFT), a non-invasive carotid Doppler-based method, could serve as an alternative, but its agreement with cLVET in CABG patients remains uncertain. This study evaluates the clinical agreement between these two measures in a real-world clinical setting.

Mapping Knowledge Landscapes and Emerging Trends in Contrast-Enhanced Ultrasound for Breast Cancer: A Bibliometric and Visualization Analysis
Breast cancer remains a leading threat to women's health worldwide and reducing mortality hinges on early detection. Contrast-enhanced ultrasound (CEUS), an emerging technique for blood-pool imaging, enables assessment of microvascular perfusion in breast lesions and addresses limitations of conventional ultrasound. Although CEUS plays an increasingly important role in breast cancer diagnosis, a comprehensive bibliometric evaluation of CEUS research in breast oncology has not yet been undertaken. This study applied bibliometric analysis to delineate the developmental trajectory of CEUS in breast cancer, identify prevailing research hotspots, and anticipate future directions. Using publications retrieved from the Web of Science Core Collection (1996 to May 2025), we conducted a systematic assessment of co-authorship patterns; institutional and national collaboration networks; journal and author productivity; and keyword co-occurrence and clustering. In total, 503 publications met the inclusion criteria, with annual output accelerating notably since 2020. China and the United States were the principal contributors, both in publication volume and collaborative partnerships. Forsberg Flemming and the Journal of Ultrasound in Medicine were identified as the most prolific author and journal, respectively. Thematic cluster analysis highlighted key research domains, including optimization of microbubble agents, diagnostic performance, treatment response monitoring and integration of artificial intelligence (AI). Collectively, these trends indicate the field's progression from a primarily diagnostic modality toward predictive, therapeutic, and real-time AI-enabled applications driven by ongoing technological innovation.

Local Delivery of miR-27a* Using Ultrasound-Targeted Microbubble Cavitation Inhibits Squamous Cell Carcinoma Growth
Ultrasound-targeted microbubble (MB) cavitation (UTMC) is an image-guided therapeutic oligonucleotide delivery platform utilizing intravenously injected gas-filled ultrasound contrast agents, which carry the therapeutic on the MB shell. During transit of MBs in the microcirculation of target tissue, ultrasound causes MB oscillation, facilitating endocytosis-independent payload uptake within insonified cells. Here, we tested the hypothesis that UTMC-mediated miR-27a* delivery will reduce tumor growth rate and result in accumulation of miR-27a* within tumor cells and the tumor microenvironment.
Longitudinal Ultrasound Imaging of an Individual Fetus In Utero Using an Echogenic Marker
High frequency ultrasound imaging has become an important tool for the study of pregnancy disorders in mouse models as it enables detailed, noninvasive characterization of in utero development.
