Common Questions and Answers about Thyroid and radioactive iodine

Avatar n tn RAIU uses a different type of radioactive iodine. It is not designed to kill thyroid cells and is reasonably safe to do the uptake, although I don't think you would want to have one done every week. RAI 131 is used to kill thyroid tissue. RAI 121 is used for uptakes scans, I think, although that may be wrong. At any rate, it is two different forms of radioactive iodine.
Avatar f tn I was pretty worried when they told me about the lung metastases, and am not sure if I should be waiting 6 months for more radioactive iodine. Or does the iodine I got last month need awhile to work on these cells? Many thanks!
Avatar f tn FionaFiat... Radioactive iodine in sufficient amounts, basically, "kills" the thyroid, so it no longer produces hormones. I've had the thyroid uptake scan and it's nothing to worry about. It's a much smaller amount of radioactive iodine and doesn't damage the thyroid (so they say)...
Avatar m tn Sometimes the thyroglobulin is not reliable. I do not know why you had a Thyrogen stimulated thyroglobulin without having had radioactive iodine. Typically when lymph nodes are involved we do give radioactive iodine. You would need to discuss the details of this with your endocrinologist.
Avatar n tn I have been hyperthyroid ever since, now I have had a radioactive iodine for my nodules and goiter, now I am a little hypothyroid and the doctors have not given any thyroid meds. I have been feeling terrible forever. My recent labs were 2.18 for TSH and .67 for my T4. Help me if you can. What should I do now?? Feeling the symptoms of both the hypo and hyper from time to time.
918011 tn?1243399744 my question is if I have nodules on each side of my thyroid, will radioactive iodine, help me? What happens to the nodules? Do they disappear? Im confused...also, when I was in my 20's, I had kidney stones and was given Iodine w/ serious effects, does the radioactive iodine pose the same threat?
Avatar m tn He recommended i get the radiation. But I have a friend whos relative is a thyroid surgery and associate professor at a university. he told me he i didnt need the radiation. i also went to see an endo doc who told me he couldnt find any reason to give me radiation. he told me the only thing is i was male and they typically have a worse prognosis but he said everything else led him that i didnt need the radiation. So, I just cant make up my mind what to do.
Avatar n tn One way to do this is by injecting thyrogen to stimulate the thyroid. Radioactive iodine is used to destroy any remaining thyroid cells including cancer cells. Important note: a low iodine diet is recommended for 1 - 2 weeks prior to RAI treatment.
Avatar n tn I believe there is radioactive iodine treatment, but from what I have learned (I have not had to deal with this problem) you would have to stay away from you son, pets and others for a while because of the radioactivity. You might want to get a second opinion from an endocrinologist.
Avatar n tn Ok this is what i have found just having a quick look! I think it might be worth while discussing this with your doctor if you haven't already done so. Maybe there may not be a need for abortion Pregnancy: The fetus begins taking up iodine into its’ thyroid at about 12 weeks gestation & exposure to radioactive iodine at this time can cause the thyroid to fail to develop. Pregnancy should be delayed four to six months after radioactive iodine therapy.
Avatar n tn Do you mean that you took the radioactive iodine pill years ago, and your thyroid was ablated?
Avatar f tn Why would they be recommending Radioactive Iodine if it was contained to my thyroid. The size of the nodule/tumor was 4 cm. Is my cancer more than likely gone or should I be concerned that this is not over yet?
Avatar f tn Any chance your doctor would do a Thyrogen stimulated ablation? This means you would be administered two shots of Thyrogen to raise your TSH in advance of your Radioactive Iodine treatment. I and many others have done Thyrogen for our RAI treatments and didn't have to go off our meds even for one day. Ask your doctor about it. My Endo is a associate professor at a teaching hospital for Harvard Medical School and is a very mainstream endocrinologist and he agreed to do Thyrogen for me.
Avatar n tn The most common thyroid cancers (papillary and follicular) are made of thyroid tissue which absorbs iodine so radioactive iodine is a *much* better way to find these cancers than radioactive glucose. Papillary carcinoma (the most frequent of the thyroid cancers) often has "micro cancers" which wouldn't show as much of anything. A thyroid ultrasound is the standard imaging technique to see if there is a suspicious nodule in the thyroid.
393986 tn?1303825975 s done with the contrast agent radioactive iodine it has damaged my thyroid. I was not aware of this until recently and I thought to myself, "They need to make the patient aware of this fact so they can decide if the test is worth the damage to their thyroid". So now I am forwarding this on to all of you because I think it is very important to us all.
Avatar f tn It was probably radioactive iodine and it was given for hyperthyroidism, not hypo. Radioactive iodine (RAI) is used for someone who has hyperthyroidism to "kill" the thyroid so it no longer produces thyroid hormones. When RAI is first given, the person must stay away from others for a specified period of time, but once that time passes, so does the danger. Could you explain why you're asking about this now?
Avatar f tn continue to monitor how you are feeling as the weeks pass and the radioactive iodine diminishes your thyroid hormone. Too often, a doctor tells you to return in a given amount of time and sometimes that is too long a time and you are feeling terrible. Get back in before you feel completely wiped out so that you can be put on thyroid meds. Best of luck.
865758 tn?1285952904 I am allergic to the Iodine based dye Pertechium so for my thyroid tests they used the newer one and I had no problems. I had the same reaction as you did with previous tracers and felt like I was going to die! Please ask your Doc for the 'low-osmolar' contrast. Hope that helps.
Avatar f tn ve reached to the point where i need surgery or radioactive iodine. My cousin had thyroid cancer last year. I am finding it hard to make a decision, which procedure is better choice long term?
Avatar n tn Called endocrinologist to see if side effect from radioactive iodine and told no. My thyroid is quite large on one side (the nurse said it looked like a "60") and just a little enlarged on the other side. It's probably just coincidental, but I took a beta-blocker right before tingling/numbness started, but I take three doses of the beta-blocker every day and have been for three months.
