Summary

This study compares a newer type of scan (I-124 PET/CT) to the standard scan (I-123 whole body imaging) for finding thyroid cancer that has spread. About 62 people with thyroid cancer will get both scans, and researchers will see if the new scan is more accurate. The goal is to improve how doctors detect and manage thyroid cancer.
