研究目的:

1)构建深度学习生成模型:基于国内人群肝脏 CT 平扫数据,开发并优化模型,实现从平扫图像精准生成动脉期、门静脉期增强图像,解决现有模型对肝 脏解剖结构适配性差、泛化性不足的问题; 2)保障生成图像诊断价值:验证生成增强图像与真实增强图像的一致性,确保其在病灶检出、定性等方面达到临床诊断标准,为后续诊断提供可靠影像依据; 3)规避造影剂相关风险:通过无造影剂的增强图像生成技术,扩大肝脏 CT 检查适用范围,满足造影剂过敏、肾功能不全等特殊人群的检查需求。  

Objectives of Study:

1) Build a deep learning generative model: Based on the plain CT scan data of the liver in the domestic population, develop and optimize the model to accurately generate enhanced images of the arterial phase and portal vein phase from plain scan images, solving the problems of poor adaptability and insufficient generalization of existing models to the anatomical structure of the liver. 2) Ensure the diagnostic value of generated images: Verify the consistency between the generated enhanced images and the real enhanced images to ensure that they meet the clinical diagnostic standards in terms of lesion detection and qualitative analysis, providing reliable imaging basis for subsequent diagnosis; 3) Avoid risks related to contrast agents: By using contrast-free enhanced image generation technology, expand the application scope of liver CT examinations to meet the examination needs of special groups such as those allergic to contrast agents and those with renal insufficiency.
