研究目的:

本项目前瞻性地收集中国医科大学附属第一医院胃癌患者的术前CT影像数据、基线数据与病理资料,以构建一种基于CT的深度学习模型,对术前CT图像进行自动的胃癌淋巴结分割,并预测其转移状态,有助于精准的肿瘤术前分期评估,指导合理的手术范围。  

Objectives of Study:

This study prospectively collects preoperative CT imaging data, clinical baseline, and pathological information of gastric cancer patients from the First Hospital of China Medical University, aiming to develop a CT-based deep learning model for the automatic segmentation of gastric cancer lymph nodes and the prediction of metastatic status. The proposed model is expected to facilitate precise preoperative staging and assist in determining the optimal surgical extent.
