Summary

This study tested a new type of PET scan (called 68Ga-MY6349) that targets a protein called Trop-2 on cancer cells. It was used in 149 adults with thyroid cancer to see if it could find cancer that had come back or spread. The results were compared to the standard FDG-PET scan to see which one worked better.
