Abstract Background Carpal tunnel syndrome (CTS) is the most common entrapment symptom in peripheral nerves. High-frequency ultrasound (HFUS) widely used diagnosis of CTS. Virtual Touch Tissue Imaging and Quantification (VTIQ), which provides more information about hardness organization, to diagnose However, data diagnostic value them various degrees CTS are limited. Whether combination HFUS VTIQ can improve efficiency also remains unknown. The study aimed explore whether could Methods A...

Objective: The objective of this study is to evaluate the gastric emptying in patients with systemic lupus erythematosus (SLE) gastrointestinal involvement using three-dimensional (3D) ultrasonography.Methods: times at 25% (T1), 50% (T2), and 75% (T3) SLE (n = 40) healthy controls 80) were evaluated compared. In addition, correlations among wall thickness, disease activity index (SLEDAI), upper symptoms calculated.Results: thickness was correlated SLEDAI (r 0.928, p < 0.001) symptom 0.848,...

Abstract The objective of this study is to develop and validate the performance 2 ultrasound (US) feature–guided machine learning models in distinguishing cervical lymphadenopathy. We enrolled 705 patients whose US characteristics lymph nodes were collected at our hospital. B-mode color Doppler features both cohorts analyzed by radiologists. decision tree back propagation (BP) neural network developed combining clinical data (age, sex, history tumor) features. was evaluated calculating area...

Background and Objective: To train a YOLO-v7-based model in the classification of cervical lymphadenopathy images compare its performance against qualitative visual evaluation by experienced radiologists.Methods : Ultrasound lymphadenopathies (2807 with benign lymph nodes, 1108 lymphomas, 4580 metastatic nodes) were retrospectively analyzed. The dataset was randomly divided into 3 subsets for training, validation, testing at ratio 18:1:1. marked using LabelImg software augmented varying...
