Summary

This study tested a new type of PET scan (68Ga-FAPI) to see if it can find lung cancer and its spread more accurately than the standard FDG-PET scan. 58 adults with known or suspected lung cancer received both scans, and results were compared to tissue samples or follow-up. The goal is to improve diagnosis and staging of lung cancer.
