FDG-PET imaging is recommended by clinical guidelines for staging of lung cancer; however, there are still limitations of FDG-PET in lung cancer staging due to false-positive and false-negative findings. 68Ga-FAPI PET images have shown high diagnostic performance with high tumor-to-background ratio in various cancers. The purpose of this study is head-to-head comparison of 68Ga-FAPI-46 PET and 18F-FDG PET for the diagnosis and staging or re-staging of lung cancer.
This is a prospective, single-center, single arm, open label study to evaluate the performance of 68Ga-FAPI-46 for the diagnosis of primary and metastatic lesions of lung cancer with comparison to 18F-FDG PET.
