Cohort study 

研究目的:

开发并验证基于多模态医学影像的非侵入性人工智能模型,用于实现胃肠道肿瘤良恶性鉴别及术前淋巴结转移(LNM)风险预测,为个体化诊疗决策提供依据。  

Objectives of Study:

Develop and validate an non-invasive artificial intelligence model based on multimodal medical images, for the purpose of differentiating between benign and malignant gastrointestinal tumors and predicting the risk of preoperative lymph node metastasis (LNM), thereby providing a basis for individualized diagnosis and treatment decisions.
