A member asked:

Will there be an uptake for i-131 during rai if there was no uptake for i-123 pre-scan for metastatic papillary thyroid cancer?

Yes.: Pre scans are pretty rare these days. But , yes, with your thyroid gone any remaining thyroid like tissue will likely take up iodine. If your tumor was larger than 1 cm rai would usually be recommended.

Possible.: Higher dose of radiodine is used with I131 treatment and can detect uptake that might be missed by I123 scan.
