Clinical Application of 68Ga-FL-031 PET in the Diagnosis and Staging of Malignant Tumors

The project's objective is to recruit patients with clinically confirmed or suspected small cell lung cancer, breast cancer, nasopharyngeal carcinoma and other tumours for 68Ga-FL-031 PET imaging and 18F-FDG PET imaging. The histopathology of biopsy or surgical specimens was taken as the final diagnostic criteria, and the presence or absence of tumour lesions was confirmed by the aforementioned imaging. The location and nature of the lesion, and the presence or absence of metastasis, were then judged. The objective was to analyse and clarify the diagnostic efficacy of 68Ga-FL-031 PET imaging for the aforementioned malignant tumours. The objective of this study is to analyse the correlation between the 68Ga-FL-031 PET imaging tumour tissue uptake value and the tumour tissue immunohistochemical staining SSTR2 target expression.

68Ga-FAPI-LM3 PET/CT Imaging in Patients With FAP/SSTR2 Positive Disease and Compared With 18F-FDG

As a new dual receptor (SSTR2 and FAP) targeting PET radiotracer, 68Ga-FAPI-LM3 is promising as an excellent imaging agent applicable to SSTR2 positive diseases. In this research, we investigate the safety, biodistribution and radiation dosimetry of 68Ga-FAPI-LM3 in healthy volunteers. Moreover, we evaluate the potential usefulness of 68Ga-FAPI-LM3 positron emission tomography/computed tomography (PET/CT) for the diagnosis of lesions in SSTR2 positive diseases, and compared with 18F-FDG PET/CT.
