Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 and older who have undergone total thyroidectomy for thyroid cancer and may have residual or metastatic disease.

Probably not a fit

Patients with cancers metastatic to the thyroid or those under 18 years old may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to assess the clinical utility of I-124 PET/CT imaging and dosimetry in patients with thyroid cancer. It focuses on evaluating the extent of remnant tissue after total thyroidectomy, distinguishing between nodal metastases and remnant tissue, and assessing responses to RAI ablation. Additionally, it will evaluate suspected recurrent or metastatic disease and the RAI avidity of recurrent thyroid cancer in patients undergoing treatment with thyroid kinase inhibitors. The study includes both newly diagnosed patients and those with known or suspected disease.

Why it matters

Potential benefit: If successful, this study could enhance the accuracy of thyroid cancer evaluations and improve treatment decisions for patients.

How similar studies have gone: While the use of PET imaging in cancer evaluation is established, the specific application of I-124 PET/CT for thyroid cancer is less common and may represent a novel approach.
