Read our Thyroid Cancer research guide →Phase 2 — Testing in a bigger group (up to a few hundred people) to see if the treatment actually works and is still safe.
This trial is testing whether a newer type of scan called I-124 PET/CT can better detect thyroid cancer that has spread to other parts of the body compared to the standard scans doctors currently use. You would receive a small dose of a radioactive iodine tracer (I-124) by mouth, then have the scan performed about 20–28 hours later. Researchers want to see if this method is more accurate at finding cancer spots that might be missed by traditional imaging.
Some people with thyroid cancer need to know exactly where cancer may have spread so they can plan the right treatment. The newer scan technology may be better at spotting these areas, which could help doctors make better treatment decisions for patients.

You would swallow a capsule containing a small amount of radioactive iodine tracer, then return for a PET scan about 20–28 hours later. The scan itself takes some time but is painless. The research team will call you for up to 5 days after your scan to check for any side effects. Some participants may have a couple of additional scans over the following days if they are part of the dosimetry (radiation measurement) group. Existing scan images from your medical records will also be used for comparison.
