- This is the last video in a series of 4 teaching videos about the thyroid gland. In this video, we’ll talk about a thyroid scan & radioactive iodine. More specifically, I'll tell you what a thyroid scan is, which tracers (Technetium/Iodine-131) to use, how to prepare for a thyroid scan and if it is a safe procedure. This is an ideal video for nursing/med students who want to know more about a commonly used nuclear medicine technique.

Thank you for watching my video. If you liked it, please consider giving it a thumbs up 👍. Feel free to let me know if you have any questions, I'd be happy to help you ☺.
Thank you so much for this very informative video, Dr. Moyaert.excellent and easy to understand video explanation and demonstration. I go for this very test in 7 days. Thanks again and very best of luck to you.
@@privateundisclosed4448 Thank you sou much. Good luck with your test! 👌💪
Hello Dr. I am reaching out hoping for some answers. When I was 20 I had RAI pill. I had lost 60pounds carrying my fourth child. Since then, I have been on Synthroid. I was doing okay UNTIL menopause came. My symptoms are all over the place. I have symptoms of both Graves and Hashimoto's. I am on 88MCG's 6 days a week. My TSH is 0.44, T3 Free is 2.8, Free T4 1.2. Are there any other test I can or should have done besides these 3. I had my ANA tested it was Positive with my Titers at 1:1280 very high. I would appreciate any help. I am struggling. I recently had an US and it showed a very small shrunken thyroid gland. Thank you.
Mam plz tell long term side affects about radio iodine 131
I am a medical student from yemen, and actually I the way you organised the information in understandable way.
Thank you sooooo much!
You're very welcome! 😍💛
Excellent presentation, very organized and informative!
i’m doing a project on nuclear medicine in 8th GRADE! honestly, i had no clue what i was doing, but this helped me very, very much! thank you sooo much.
I'm so glad to hear this. Good luck with your project!🙏👌💪
EXCELLENT video and perfect and clear explanation!!
Thank you 😊😊
Very informative! So much so that I linked your video in the description box of one of my videos.
Thank you so much, Quick Med! Really appreciate it. 🧡
you're slides are amazingly great!
Oh thank you!😍
dr Moyaert , im in love with your series
💛💛💛
Excellent presentation
Thank you ❤
Wonderful explanation!
I'm so glad you decided to do these videos.
I'm going through VH NM THYROID DOSE tomorrow and not sure if I need to be separated from my son.
Many doctors failed trying to help me took 3 good years till I came in contact with DR OKOUROMI and cured me from hypothyroidism in less than 3 weeks....
🥰🥰 #DROKOUROMI
Hope it all went well.
Highly appreciate for the video I have an exam in 2 days time and this video open my mind on what I didn't understand in the lecture notes
I'm very glad I could help. Good luck with your exam! 💪😊
@@dr.paulinemoyaert thank you🌹
I recently had Total thyroidectomy because i had papillary thyroid cancer of stage 1...is it really necessary to do radioactive iodine therapy?
Great Teaching Video.
Thank you 😊
Thank you for the info
I have several facial piercings. Can I keep them in? I just got my lower lip, and one nostril repierced recently, so I can't take them out. The other three can be taken out because they have healed.
Great video! Thank you. I had what they tell me Graves disease when I was 21. I was given a pill RAI and my uptake took 3 seconds which confirmed the hyperthyroidism. I then became what they tell me (they meaning the many endocrinologist) It's frustrating as I was told I had Graves, Hashimoto's now Graves again. What are the best test to have to determine what one actually has. I have symptoms of both of these DIS eases. Thank you.
I'm so sorry, I am a nuclear medicine physician, not an endocrinologist. I'm afraid I can't help you with this 😢
I had the needle biopsies on my thyroid and have hypothyroid problem with thyroid and I was wondering what medication I should have or not.
This is something your doctor should tell (and prescribe) you. 😉
Thank you so much!!
You're welcome! 😊
Great .. thanks!
Thanks Mohamed! ☺
Isl this pill we are given completely safe?
Thank you..i have hyperthyroid..next year i have money i will do scan to my thyroid.hopefully i will have money..this is going to be very expensive
I hope so too!
For Grave's disease, is Iodine 131 treatment always successful ? or it there a chance of failure or relapse afterward ?
Thanks Dr Paulien:)
Not always, but in many cases. If it is not successful, we can give a seconde dose of Iodine 131 :)
What about papillary thyroid cancer doctor, after total thyroidectomy.... Is it a must?
I'm sorry, but I don't think I understand your question
In Graves’ disease there is hyperactive gland, so they are on thiourea drugs because TSH is low, so what is done to get the TSH levels high?
Nothing, we want T4 levels to be high. The fact that TSH levels remain low is not important and has no clinical impact.
@@dr.paulinemoyaert in the video it says for iodine uptake it’s best if TSH is high.
@@manalnadeem3350 where exactly? Can you give me the seconds please?
At 3:40, sorry I’m just a little confused
@@manalnadeem3350 at 3:40, I'm talking about radioactive iodine treatment. Treatment to treat a hyperactive thyroid. We want the TSH as high as possible, because that means that the thyroid will take up a lot of the radioactive iodine (you could say that the thyroid is "hungry"). People stop taking their T4 pills a few days before this treatment, this will cause the TSH to rise.
What is the difference between cold nodule and hot nodule
Hi! A hot nodule is a nodule that produces excess thyroid hormone and will show up on a thyroid scan (because they take up more of the isotope than normal tissue does). Hot nodules are almost always noncancerous. A cold nodule, on the other hand, is a nodule that takes up less of the isotope and is often cancerous.
Hi Dr. Paulien, thank you so much for such a valuable video. I request you to please take a moment to see my case.
My blood tests diagnosed me with Hyperthyroidism, however the normal ultrasound scan showed it’s normal.
Now, I’m recommended to go for a Thyroid uptake and scan. It’s mentioned in the requisition that it’s a 2 day exam. On the first day, I’ll be given a radioactive pill and on the second day, my neck will be monitored and then afterwards I’ll be given an injection in the arm.
1. I’m lil scared if it’s safe? Any side effects? Most importantly, any risks?
2. What’s your opinion about my case: I mean which Thyroid disease it looks like from your experience?
Hoping that you’ll reflect your insights.
Best Regards,
I would definitely go for the thyroid uptake scan. It's safe, the amount of radioactivity they will inject is very low. You won't feel anything at all. I would only recommend to not come close to newborn babies or pregnant women. In my opinion, not having your thyroid uptake scan and therefore maybe not getting the right diagnosis is a lot 'riskier' than having the scan.
I can't say what thyroid disease you have, I don't know where you're from, what your age or medical background is, I'm sorry.
Hi doctor, i have a question too.
On October i have a thyroid uptake and scan. My worries is that, i have 2 toddler it safe to be with for them after my uptake scan? Thank you, i hope you will reply
Hello, v informative video,loved it!
I would like to ask you a few things,
1) Is any preparation needed before the procedure -Scintigraphy?
2) why is salivary gland's uptake important,as a part of thyroid scan?is it only for the indication pain in the gland (side effect) or something more?
3) Is radioiodine uptake a part of only Scintigraphy and Ca thyroid treatments?
No preparation is needed. There's uptake in the salivary glands because they also take up tracers. It's just something you should know, it does not have any significance.
And I don't understand question 3, I'm sorry 😉
@@dr.paulinemoyaertokay.. thanks a lot for your pompt reply..
3)Just wanted to know if radioisotopes are used for elsewhere in nuclear medicine except for thyroid scan and cancer therapies.:)
@@Rebecca75100 Yes! Definitely, we use it for a variety of reasons (prostate cancer, cancer in general, osteoporosis, etc.)
@@dr.paulinemoyaert okay..thanks a lot doc!
I am taking madicine of hyperthyroidism for 3 years and now my thyroid reports T3 T4 and TSH all are normal now doctor recommended me not to take medication and take radioactive iodine to completely cure it
What you say about it
What should I do
I'm sorry Ahmad, I can't give any medical advice. 😕
Many doctors failed trying to help me took 3 good years till I came in contact with DR OKOUROMI and cured me from hypothyroidism in less than 3 weeks....
🥰🥰 #DROKOUROMI
Cold nodule golitre ( isthmus) is it Cancer?
I'm sorry Lamia, I can't give any medical advice. I hope you find someone who can help you with this question.
I got the I-123 2 days ago when can I carry my baby again?
Almost immediately after the scan . I-123 isn't dangerous, you'd have to be more cautious after an I-131 scan. So after 2 days, you can definitely carry your baby again :)
Thank you so much, I loved your video its so easy to understand and very informative!
@@estefaniapita You're very welcome! ☺
Thank you for the information doctor. Perfect presentation. I have been diagnosed with Graves disease two weeks ago. I can't wait to get the radioactive iodine therapy as it's what I opted for. How soon will I gain my weight back? An estimation please. I'm skin and bones right now. I have been grieving for a loved one for over a year so we all thought the weight loss was due to grief.
I think it will take a couple of months, depending on how much you eat and how fast your thyroid levels go back to normal.
Just wanting to know if this increases the risk of other cancers pls ❤
Hi Shivani, thank you for your comment 😊. Thyroid scans use ionizing radiation and we know that radiation exposure increases the risk of cancer. However, for thyroid scans, the effective radiation dose is only 3.2 mSv (for comparison: a CT scan of the abdomen exposes a person to about 10 mSV). 3.2 mSv is super low, so yes, it increases your risk of cancer, but it is negligible. The benefits of having the scan far outweigh any potential risk from the small radiation dose 😉
The same is true for other scans, if you want to put things in perspective, I'd recommend watching this video (3:08-3:45): th-cam.com/video/TresR2wSw40/w-d-xo.html
