According to an article published in the January 2012 issue of Archives of Internal Medicine, exposure to iodinated contrast media during imaging procedures is associated the changes in thyroid function, especially hyperthyroidism. Reactions to the dyes are increased in people with asthma, heart disease, kidney disease, and in those taking NSAIDs, beta blockers, and metformin. There is about 20 mg of iodine in the usual injection, which is far less than what was administered to many people who were protecting against the Fukushima nuclear disaster.
These contrast media are good to help diagnose arterial blockages, cancers, and the outline of any duct system in the body.
