Radiomics features were extracted from ultrasound images using PyRadiomics, and deep learning features were obtained using a Vision Transformer (ViT) . Feature selection was performed using least absolute shrinkage and selection operator (LASSO) regression. Multiple machine learning models were developed, and their performance was evaluated with the area under the curve (AUC) . The DeLong test was used for model comparison. Results The proportion of FISH-positive cases ranged from 9. 7% to 20. 0% across the six centers. The fusion model combining ViT and radiomics signatures consistently outperformed the individual models in the training, test, and all external validation cohorts. The AUCs ofthe fusion model were 0.887 in the training cohort, 0.799 in the test cohort, and 0 . 763, 0 . 796, 0 . 734, and 0.632 in the four external validation cohorts, respectively (all P \u003C 0. 05) .  \nConclusion The proposed ultrasound-based fusion model enables accurate prediction of FISH assay results in HER2 (2+) breast cancer patients and may serve as a reliable decision-support tool to reduce unnecessary FISH testing in clinical practice.  \n†Cong Jiang, Dong Chen, Xiao Yu, Shentao Zhang andYuting Xiu contributed equally to this work.  \n*Correspondence:  \nZiyu Zhu [243823456@qq.com](243823456@qq.com)[ ](243823456@qq.com)Yuanxi Huang [rxwk@163.com](rxwk@163.com)  \nShipeng Ning [nspdoctor@sr.gxmu.edu.cn](nspdoctor@sr.gxmu.edu.cn)[ ](nspdoctor@sr.gxmu.edu.cn)Shicong Tang [tang_shicong@126.com](tang_shicong@126.com)  \nFull list of author information is available at the end of the article  \n© The Author(s) 2026.
