Clinical Investigator-Initiated Trial (IIT) of PD-L1-Targeted Radionuclide Probes

According to the inclusion and exclusion criteria, 50 patients with solid tumors were selected. The first 5 subjects completed 45 minutes dynamic scan image acquisition, and then static scan was performed at subsequent time points. Each subject completed at least 1 hour and 2 hours of static acquisition, and 3 hours of image acquisition depending on the subject's physical condition and other comprehensive factors). Within 3 months after the subjects completed the examination, the researchers will retrieve the subjects' electronic medical records through the medical record system or telephone interview. The laboratory examination results, pathological results, and other imaging comprehensive diagnosis results of the subjects were collected, and the changes of lesions were observed. The expression level of PD-L1 in traditional tissue biopsy was compared with the results of \[18F\]F-PDL1-3 PET/CT examination.
