Description:

This is a prospective, single center, single-arm clinical trial in 20 patients with non-small cell lung cancer (NSCLC) undergoing PD-1/PD-L1-directed therapy. This research is being done to find out if the radioactive compound called [18F]F-AraG is a helpful imaging agent for detecting changes in cancer's anti-tumor immune response (or activation of T-cell) levels for non-small cell lung cancer (NSCLC) patients who will receive a cancer immunotherapy regimen (immunotherapy works by encouraging the body's own immune system to attack the cancer cells).
