BackgroundRadioiodine-refractory thyroid carcinomas (RAIRs) are characterized by reduced expression of sodium–iodine symporter, rising serum thyroglobulin levels, and negative whole-body radioiodine scans. Interestingly, RAIRs continue to express somatostatin receptors and can be identified with 68G
