Study Summary

Persons diagnosed with thyroid cancer are often treated initially with a thyroidectomy, which is followed by ablation using Iodine-131, a therapy which has been shown to be effective and safe. Imaging of metastatic thyroid cancer has been performed with whole body I-131 and Iodine 123 (I-123) imaging for many decades and use I-123 for staging studies. Iodine 124 (I-124) is a radioisotope of iodine which emits a positron and is imaged using PET (positron emission tomography). This is a single arm prospective trial that evaluates the ability of Iodine-124 (I-124) to detect metastatic thyroid cancer compared to non-interventional, usual care I-123 and I-131 images.

Primary Outcome

Participant-level agreement between I-124 PET and the combination of I-123/I-131 SPECT will be measured. A participant will be classified as showing agreement only if all six regions demonstrate agreement; disagreement in one or more regions will result in a classification of disagreement. Positive percent agreement (PPA) and negative percent agreement (NPA) will be reported with corresponding 95% confidence intervals.
