PET scan imaging to detect tumors using amino acid tracers

This trial is testing a specialized PET/CT imaging scan that uses amino acid tracers (11C/18F-MET/FET) to detect and monitor tumors. The scan works by injecting a small amount of radioactive tracer into your bloodstream, which accumulates in tumor cells and shows up on imaging. Researchers want to measure how accurate this imaging method is for finding tumors and detecting whether cancer has returned after treatment.

Current imaging methods sometimes miss tumors or cannot clearly distinguish between tumor tissue and normal tissue. This trial is exploring whether amino acid-based imaging might be more accurate at finding tumors earlier and monitoring patients more effectively after treatment.
