The iodide dye used in heart scans and other medical imaging might damage some people's thyroid glands, which could cause important health problems later on, researchers say.

In a new study, they found patients who had signs of thyroid disease were between two and three times as likely to have had a scan using iodide as a comparison group of people without thyroid problems.

The findings aren't ironclad proof that the dye itself is responsible, but experts agree that's a likely explanation since high doses of iodide are known to throw the thyroid off balance.

And the amounts typically given during a scan may be several hundred times greater than the recommended daily intake of 150 micrograms.
