NCT ID NCT03647358

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tests a new PET scan using a special form of iodine called iodine-124 to measure how much radioactive iodine thyroid cancer tumors absorb. The goal is to help doctors decide if standard radioactive iodine therapy is likely to help. About 60 adults with metastatic thyroid cancer will receive an oral dose of iodine-124 and undergo up to four PET scans over several days.

Iodine-124

What this could lead to

If successful, this imaging test could help doctors decide whether radioactive iodine therapy will work for each patient, avoiding ineffective treatments.
