研究目的：

本项目拟在临床已确诊或高度怀疑表达CLDN18.2的胃癌、胰腺癌、胆管癌等恶性肿瘤患者及健康志愿者中，应用靶向CLDN18.2的PET显像剂（以68Ga-NOTA-CLDN18.2抗体片段为例），开展一体化PET/MR或PET/CT显像研究，旨在实现以下目的： 恶性肿瘤患者：用于肿瘤的早期诊断、分期与治疗评估。通过与金标准病理结果对比，评估68Ga-CLDN18.2 PET显像在定位肿瘤病灶、判断病灶性质（良恶性）、明确转移范围等方面的诊断准确性；同时与18F-FDG PET进行对比分析，探索其在识别低代谢活性或FDG低摄取肿瘤中的优势，辅助制定更精准的治疗策略，并为CLDN18.2靶向治疗患者筛选提供依据。 健康志愿者：开展初步的药代动力学和安全性研究，明确68Ga-CLDN18.2显像剂在人体内的分布、代谢途径、排泄方式及潜在不良反应，为后续大规模临床应用和影像剂的注册转化奠定基础。  

Objectives of Study：

This project plans to apply a targeted CLDN18.2 PET imaging agent (taking 68Ga-NOTA-CLDN18.2 antibody fragment as an example) to conduct integrated PET/MR or PET/CT imaging studies in patients with malignant tumors such as gastric cancer, pancreatic cancer, bile duct cancer, etc. that have been clinically diagnosed or highly suspected to express CLDN18.2, as well as healthy volunteers. The aim is to achieve the following objectives: Malignant tumor patients: Used for early diagnosis, staging, and treatment evaluation of tumors. By comparing with the gold standard pathological results, evaluate the diagnostic accuracy of 68Ga-CLDN18.2 PET imaging in locating tumor lesions, judging the nature of lesions (benign or malignant), and defining the extent of metastasis; at the same time, compare and analyze it with 18F-FDG PET to explore its advantages in identifying tumors with low metabolic activity or low FDG uptake, assist in formulating more precise treatment strategies, and provide a basis for the selection of patients for CLDN18.2 targeted therapy. Healthy volunteers: Conduct preliminary pharmacokinetic and safety studies to clarify the distribution, metabolic pathways, excretion methods, and potential adverse reactions of 68Ga-CLDN18.2 imaging agent in the human body, laying the foundation for subsequent large-scale clinical applications and the registration transformation of imaging agents.
