    Modern diagnostics: ultrasound elastography and magnetic resonance imaging in initial evaluation of testicular cancer

    Şeref Barbaros Arik1,2,*, İnanç Güvenç1,2

    Canadian Journal of Urology, Vol.32, No.6, pp. 569-578, 2025, DOI:10.32604/cju.2025.068094 - 30 December 2025

    Abstract Objectives: Differentiating benign from malignant testicular lesions is essential to avoid unnecessary surgery and ensure timely intervention. While conventional ultrasound remains the first-line imaging method, elastography and MRI provide additional functional and structural information. This study assesses the diagnostic utility of testicular elastography and magnetic resonance imaging (MRI) in differentiating benign and malignant testicular lesions. Methods: Patients with sonographically detected testicular masses were retrospectively evaluated using elastography, scrotal MRI, and tumor markers. Quantitative and qualitative imaging findings, lesion size, and laboratory values were recorded. Statistical analyses included Fisher’s exact test, logistic regression, Receiver operating characteristic… More >

    Joon Yau Leong1, Tyler Gaines2, Zachary J. Prebay1, David Ebbott1, Paul H. Chung1,*

    Canadian Journal of Urology, Vol.32, No.6, pp. 589-595, 2025, DOI:10.32604/cju.2025.064125 - 30 December 2025

    Abstract Introduction: Despite the diagnostic value of intracavernosal injections (ICI) and penile Doppler ultrasound (PDUS), there remain barriers to widespread clinical adaptation of these methods. The study aimed to evaluate the practice patterns of utilization of ICI and PDUS in the assessment of erectile dysfunction (ED) and Peyronie’s disease (PD). Methods: Using the TriNetX database (Cambridge, MA, USA), adult (≥18 years) male patients with a diagnosis of ED on oral phosphodiesterase-5 (PDE5) inhibitors were identified. Current Procedural Terminology codes were utilized to identify patients who underwent further evaluation with ICI or PDUS, as well as penile… More >

    A Computational Modeling Approach for Joint Calibration of Low-Deviation Surgical Instruments

    Bo Yang1,2, Yu Zhou3, Jiawei Tian4,*, Xiang Zhang2, Fupei Guo2, Shan Liu5,*

    CMES-Computer Modeling in Engineering & Sciences, Vol.145, No.2, pp. 2253-2276, 2025, DOI:10.32604/cmes.2025.072031 - 26 November 2025

    Abstract Accurate calibration of surgical instruments and ultrasound probes is essential for achieving high precision in image guided minimally invasive procedures. However, existing methods typically treat the calibration of the needle tip and the ultrasound probe as two independent processes, lacking an integrated calibration mechanism, which often leads to cumulative errors and reduced spatial consistency. To address this challenge, we propose a joint calibration model that unifies the calibration of the surgical needle tip and the ultrasound probe within a single coordinate system. The method formulates the calibration process through a series of mathematical models and… More >

    Surelys Ramos-Bell1, Edson Rayón-Díaz1, Juan A. Herrera-González2, Estefanía Martínez-Batista1, Rita M. Velázquez-Estrada1, Porfirio Gutiérrez–Martínez1,*

    Phyton-International Journal of Experimental Botany, Vol.94, No.10, pp. 3145-3156, 2025, DOI:10.32604/phyton.2025.071543 - 29 October 2025

    Abstract A significant portion of losses in the fruit and vegetable sector are caused by the necrotrophic fungus Botrytis cinerea, due to its high prevalence in over 1000 crop species. Identifying a technology capable of exclusively inhibiting its growth and development remains challenging; therefore, various treatments have been proposed to act synergistically in preventing the spread of this pathogen. The objective of this study was to evaluate an ultrasound-assisted treatment combined with chitosan to control the development of B. cinerea. In vitro analyses showed that combining temperature, ultrasound, and chitosan inhibited the fungal radial growth by 80%, reduced sporulation, More >

    Ultrasonic Modification of Wood Surface: Study of Macro and Micro Properties after Long-Term Storage

    Alena Vjuginova1,*, Leonid Leontyev2

    Journal of Renewable Materials, Vol.13, No.9, pp. 1819-1828, 2025, DOI:10.32604/jrm.2025.02025-0061 - 22 September 2025

    Abstract In this paper, the stability of the results of ultrasonic wood surface modification after long-term storage, including macroscopic properties and microstructure of specimens, was investigated. Specimens of aspen wood (Populus tremula) were processed by the developed ultrasonic method of wood surface modification in three different treatment modes and the surface hardness of the specimens was evaluated after processing and after storing the specimens for more than 5 years since long-term stability is an important factor for the use of ultrasonically modified sawn timber as construction and finishing materials. The obtained results of surface hardness measurements by… More > Graphic Abstract

    A Method for Ultrasound Servo Tracking of Puncture Needle

    Shitong Ye1, Bo Yang2,*, Hao Quan3, Shan Liu4, Minyi Tang5, Jiawei Tian6,*

    CMES-Computer Modeling in Engineering & Sciences, Vol.144, No.2, pp. 2287-2306, 2025, DOI:10.32604/cmes.2025.066195 - 31 August 2025

    Abstract Computer-aided surgical navigation technology helps and guides doctors to complete the operation smoothly, which simulates the whole surgical environment with computer technology, and then visualizes the whole operation link in three dimensions. At present, common image-guided surgical techniques such as computed tomography (CT) and X-ray imaging (X-ray) will cause radiation damage to the human body during the imaging process. To address this, we propose a novel Extended Kalman filter-based model that tracks the puncture needle-point using an ultrasound probe. To address the limitations of Kalman filtering methods based on position and velocity, our method of More >

    Dual-Classifier Label Correction Network for Carotid Plaque Classification on Multi-Center Ultrasound Images

    Louyi Jiang1,#, Sulei Wang1,#, Jiang Xie1, Haiya Wang2, Wei Shao3,*

    CMC-Computers, Materials & Continua, Vol.83, No.3, pp. 5445-5460, 2025, DOI:10.32604/cmc.2025.061759 - 19 May 2025

    Abstract Carotid artery plaques represent a major contributor to the morbidity and mortality associated with cerebrovascular disease, and their clinical significance is largely determined by the risk linked to plaque vulnerability. Therefore, classifying plaque risk constitutes one of the most critical tasks in the clinical management of this condition. While classification models derived from individual medical centers have been extensively investigated, these single-center models often fail to generalize well to multi-center data due to variations in ultrasound images caused by differences in physician expertise and equipment. To address this limitation, a Dual-Classifier Label Correction Network model… More >

    Abstract Background: Patients with Fontan physiology are predisposed to congestive hepatopathy, progressive liver fibrosis, and end-stage liver disease. Ultrasound-based shear wave elastography (SWE) is a non-invasive tool to diagnose and monitor liver fibrosis. We sought to determine whether the degree of hemodynamic derangement prior to and after the Fontan operation is associated with increased liver stiffness measured by SWE. Methods: A single-center retrospective study of patients with Fontan circulation who underwent ultrasound elastography between 2008 and 2024 was conducted. Liver stiffness was measured by SWE and reported as velocity in m/s. Hemodynamic assessment with cardiac catheterization and… More >
