Hello there, I had a stem cell transplant in May of 2010, I am scheduled to have a followup pet scan for lymphoma. I am also scheduled to have RAI for papillary thyroid cancer. My thyroid doc said that I have to be four months without a petscan before they can do the RAI. If I have the petscan first, does anybody know how long is the period I have to wait before I can do the RAI after the scan?
