hi all, have a few questions about rai, i am due to have my first injection tomorrow and then my tablet on thursday, i am having the 3.7 dose, i am told that is medium dose. i am a little confused as some people are offered the iodine thyrogen stimulated whold body scan before the rai to see how much uptake there is and how much thyroid is still there to work out what dose to give you. my oncologist says as I had lymph node involvement i should have the medium dose, but would it not be wise to have the scan before to see if i might only need the 1.1 (lower dose of radiation). feeling really stressed and worried that i am doing the right thing putting radioactive stuff in my body. thank you
