The usage of iodine as a contrast media??and as a substance for thyroid usage??is just a coincidence.
Iodine for thyroid is obvious cos thyroid stores iodine for thyroid hormone synthesis.
Oral Lugol¡¯s iodine,radioiodine and K iodide are for thyroid conditions?
Another BIPP an iodine bismuth paste is for ENT packing use
Povidine iodine is used for antiseptic prior to surgical procedures.
So it appears iodine is commonly used in the medical profession come to think of??it
Iodine for contrast is explained clearly in this file
From my google search some free iodide present in the contrast may interfere with some thyroid test.
