No speedy1. They did not. They used Iodoral, because it had the right portion of Iodine with potassium iodide, same as Lugol's solution. I think they were testing for fibrocystic breast disease; but I'm not sure. Some organs of the body will use Iodine better than iodide. I'll try to find that list. I do know that it is Iodine that found in the breast tissue and I think the prostate.
