I had TT Feb 2007, had bodyscan and RAI in early March of 2007 and had bodyscan on anniversary Feb 2008. I have never been told to go on a low idiodine diet, when I brought it up - they said it was not necessary. I did have the thyrogen shots before the scan this year, etc............all went well, no cancer. So, I think there is a lot of disagreement regarding this low iodine diet thing and in general with how thyroid cancer patients are handled with follow-up, etc....
