Special Imaging Scan to Guide Thyroid Cancer Treatment

This trial is testing a special type of imaging scan called I-124 PET/CT that takes detailed pictures to help doctors see thyroid cancer more clearly. The scan may help doctors decide whether you need radioactive iodine treatment, check how well your treatment is working, or find cancer that may have come back or spread to other parts of your body.

Standard imaging methods sometimes can't clearly tell the difference between normal leftover thyroid tissue and cancer that has spread, or they may miss small areas of disease. This trial exists to see whether this new imaging scan can give doctors better information to make treatment decisions and monitor how well your cancer is responding to therapy.
