NCT ID NCT07436455

First seen Feb 28, 2026 · Last updated May 16, 2026 · Updated 8 times

Summary

This study compares a new PET imaging agent, F-18 TFB, with the standard FDG PET/CT to find leftover thyroid cancer in 50 patients who have had surgery and radioactive iodine therapy. Participants have high levels of thyroglobulin (Tg) in their blood, which may signal cancer, but standard scans are unclear. The goal is to see if F-18 TFB can more accurately detect cancer lesions, helping doctors decide on further treatment.
