Abstract Purpose Large language models (LLMs) are pivotal in artificial intelligence, demonstrating advanced capabilities natural understanding and multimodal interactions, with significant potential medical applications. This study explores the feasibility efficacy of LLMs, specifically ChatGPT-4o Claude 3-Opus, classifying thyroid nodules using ultrasound images. Methods included 112 patients a total 116 nodules, comprising 75 benign 41 malignant cases. Ultrasound images these were...

Post-pandemic workforce demands in Wales have resulted an increase radiography students, causing imbalance between student numbers and clinical placement learning opportunities. Simulation-based education (SBE) has been effectively implemented several healthcare professions to replace hours enhance equity. This study aimed address the limited scope of literature surrounding this approach within diagnostic Wales, by exploring perceptions a Simulated Clinical Placement (SCP) package one...

Thyroid cancer diagnosis has evolved to include computer-aided (CAD) approaches overcome the limitations of human ultrasound feature assessment. This study aimed evaluate diagnostic performance a CAD system in thyroid nodule differentiation using varied settings.Ultrasound images 205 nodules from 198 patients were analysed this retrospective study. AmCAD-UT software was used at default settings and 3 adjusted diagnose nodules. Six risk-stratification systems classify nodules: The American...

Although multimodal ultrasound approaches have been suggested to potentially improve the diagnosis of thyroid cancer; diagnostic utility combination SWE and malignancy-risk stratification systems remains vague due lack standardized criteria. The purpose study was assess value grey scale assessment using EU TIRADS shear wave elastography. 121 patients (126 nodules−81 benign; 45 malignant) underwent imaging nodules between 0.5 cm 5 prior biopsy and/or surgery. Nodules were analyzed based on...

This study investigated the diagnostic value of Angio Planewave Ultrasensitive (AngioPLUS) Doppler ultrasound in improving efficacy grey scale thyroid nodule diagnosis. The EU TIRADS was used for assessment 94 nodules. conventional and AngioPLUS images were evaluated using qualitative vascularity grading, where predominant central indicated malignancy-suspicion, quantitative regional assessment, peripheral a ratio index (RVI) > 1 benign disease. Diagnostic performance outcomes sole...

Abstract Purpose Thyroid nodules are highly prevalent in the general population, posing a clinical challenge accurately distinguishing between benign and malignant cases. This study aimed to investigate diagnostic performance of different strategies, utilizing combination computer-aided diagnosis system (AmCAD) shear wave elastography (SWE) imaging, effectively differentiate thyroid ultrasonography. Methods A total 126 with pathological confirmation were prospectively included this study....

Microvascular ultrasound imaging techniques such as Angio PLanewave UltraSensitive (Angio-PL.U.S.) have been used to detect microvascular blood flow in various organs and tissues. However, the advantage of Angio-PL.U.S. for assessing muscle microvascularity over other non-invasive modalities has not investigated. This cross-sectional study compared ultrafast conventional color Doppler (CDFI) intramuscular perfusion. Forty-five older adults participated (age = 59.1 ± 7.6). The vascularity...

The value of computer-aided diagnosis (CAD) and computer-assisted techniques equipped with different TIRADS remains ambiguous. Parallel performances subjective assessments CAD were compared based on AACE, ATA, EU, KSThR TIRADS. software computed the 162 thyroid nodule sonograms. Two raters (R1 R2) independently rated sonographic features nodules using an online risk calculator while blinded to pathology results. Diagnostic efficiency measures calculated final R1 had higher diagnostic...
