Dexa?iodide saturate: Not sure 'bout DEXA (?Bone density scan?); ki is elemental iodine which is taken up by thyroid. Thyroid needs iodide to make thyroid hormone, but taking ki can cause either hyper- or hypo- thyroidism. Ki was used in japan after nuclear accident to keep people's thyroid from taking up radioactive iodine.
