Which is a possible contraindication to the use of radioactive iodine? The use of salt substitute, presence of a goiter, or shellfish allergy

Eye disease: For patients with graves' orbitopathy (bulging eye/s), the eyes might get worst with radioactive iodine. This is a relative contraindication as we can treat with steroids to lessen the effects or prevent this from happening. The three scenarios you described above are not contraindications, however.

Radioactive (Definition)

Radioactivity refers to the particles which are emitted from nuclei as a result of nuclear instability. Because the nucleus experiences the intense conflict between the two strongest forces in nature, it should not be surprising that there are many nuclear isotopes which are unstable and emit some kind of radiation. The most common types of radiation are called alpha, ...Read more

Is radioactive iodine safe if I have multiple health issues?

Generally yes: If you're referring to radioactive iodine for treatment of hyperthyroidism, it's probably the safest treatment. Not associated with birth defects, cancer, leukemia etc. Much safer than not treating the hyperthyroidism, particularly if you have "health issues". There are also oral anti-thyroid pills. Surgery has potential risks and should be avoided except in special cases.

What are symptoms of getting radioactive iodine from a patient?

What are symptoms of getting radioactive iodine from a patient?

Radio active: Wrong question. You need to work hard to avoid that happening. If possible don't share a bathroom or toilet for a week after getting the radioactive iodine. If not feasible one of you must wait an hour or longer before sharing toilet facilities.

Radioactive iodine versus partial thyroidectomy, explain please?

Radioactive iodine versus partial thyroidectomy, explain please?

Need more info: Radioactive iodine is often used for graves' disease which is a hyperactive thyroid condition. I am assuming you were given this option or partial thyroid removal to control the problem. The radioactive therapy is usually preferred but sometimes surgery is better depending on many issues. You need to discuss with endocrinologist and surgeon.

Is it safe to be near a person who has had radioactive iodine for?

Is it safe to be near a person who has had radioactive iodine for?

Yes: As long as you're at normal conversational distances, there's really almost no risk. There is a risk, however, to a small child or infant that is held close to your neck for an extended period of time. The radioactivity level drops down quickly in usually about 2 days.

What can I expect after radioactive iodine therapy?

What do I need to know about radioactive iodine treatment in australia?

The same as in USA: Rai can be used to treat hyperthyroidism and thyroid cancer. Are you contemplating emigrating to australia? Talk to an american nuclear technologist first to find out if he/she knows someone in the society of nuclear medicine in australia.

Can you tell me some exercise after radioactive iodine treatment, i-131?

Can you tell me some exercise after radioactive iodine treatment, i-131?

RAI: Hi. Was the 131-I for hyperthyroidism or for thyroid cancer? Once your hypothyroidism is treated and you stably have normal thyroid function (or slightly hyper if thyroid cancer), you're good to get back to your pre-illness workout routine. Be patient...you've been thru a lot. But go for it. You'll get back in your groove. To your health!

I am having radioactive iodine 131 treatment in two weeks, do you have any tips for me?

Radioactive iodine: Eat low I foods and avoid high I products (kelp, certain vitamins, certain cold/cough remedies). Is this for hyperthryroidism or cancer? If for hyperthyroidism, you need to wait 3-4 days, and then you can resume your (other) treatments, eg methimazole. But discuss this with your doctor. It may take 3-4 months for the rai to ablate the thyroid. Watch for symptoms of hypo.

What to if I am having radioactive iodine 131 treatment in two weeks, does anyone have any tips for me?

Follow instruction: Just follow the instructions from your doctor, and from the nuclear medicine docs. You may have been given written instructions. Read them. Avoid dietary iodine. Follow instructions on medications, esp thyroid-related drugs (methimazole, levothyroxine, etc). If this is for graves disease, you may want to take/resume a b-blocker after the treatment since T4 and T3 (liothyronine) may increase transiently.

After radioactive iodine 131 treatment how long should you wait to have small children back in your care if you recover at home not hospitalized?

To treat what?: If hyperthyroidism ok in one day - but not to have them in your lap. If for thyroid cancer wait a few days - the nuclear facility will want to do a post rai scan in about 3 days - so ask them based on any uptake when it would be safe.

To ablate remnant tissue after complete thyroidectomy (initially had multiple noduls, 1-ca node), what maximum dose of radioactive iodine be taken?

Depends: The dose is related to the risk of recurrent disease. The larger the primary tumor, the higher the risk. In your age group (under 45 yo) the risk is relatively low, even with having a positive lymph node. The recommended dose would be as low as 30 mci or as high as 100.

How long after a complete thyroidectomy and radioactive iodine until you get your stamina back? My surgery was october 19, 2010 and ri was done nov 30

Post thyroidactomy: You should feel normal (if not hyper) after around 3-4 weeks from starting your thyroid replacement therapy. Not feeling well. Is usually due to both either over or under replacement. Check your levels and adjust treent.

What kind of doctor performs "radioactive iodine ablation"?

Nucl Medicine/Endo: The licensing requirements are such that this procedures is only done by nuclear medicine physicians, and often only in larger medical centers. The endocrinologist, however, should be the one working up the condition and preparing the patient for the procedure.

What are the benefits of radioactive iodine therapy for hyperthyroidism?

What are the benefits of radioactive iodine therapy for hyperthyroidism?

Avoid surgery: Rai is designed to "kill" the thyroid without the need for surgery and surgical complications. The side effects of rai are few and manageable if done properly. Once your thyroid is dead, then you will need to take synthroid, (thyroxine) but that is easy... Much easier than taking antithyroid drugs like methimazole. You need an endocrinologist to guide you through this.

Does radioactive iodine destroy the entire thyroid? If so, why?

Does radioactive iodine destroy the entire thyroid? If so, why?

RAI...: Radioactive iodine is used for many conditions such as graves disease, thyroid cancer, and hyperfunctioning/autonomous nodules. In each case, a particular dose of radioactive iodine is used to achieve the desired result. Each case is individual and will decide how much of the gland needs to be damaged.

Will radioactive iodine treatment hurt my child in the long run?

Will radioactive iodine treatment hurt my child in the long run?

Simple answer is no: Although long term data is lacking, the current guidelines recommend rai as first choice for treatment of hyperthyroidism/Grave's (in the US) if child's age is above 7yrs of age. Medication and surgery are other options and each choice has it's pros and cons. I personally tend to opt for pharmacologic treatment if presentation is mild. Talk with your endocrinologist.

What can I expect after getting radioactive iodine on my thyroid?

What can I expect after getting radioactive iodine on my thyroid?

Improvement: Radiation treatment is designed to render non-functional the hormone producing cells of the thyroid in cases of overactivity. You can expect to have an improvement in your symptoms and a feeling of well being. You probably will need to supplement your body with thyroid hormone to replace the loss from these cells that no longer work.

What is the definition or description of: radioactive iodine uptake?

Uptake by thyroid: It is a number to rate how your thyroid gland incorporates iodine relative to a dose to help determine if your thyroid gland is functioning properly, compared to know normal uptakes for the nuclear medicine facility.

Going in for a radioactive iodine uptake scan. How is this administered?

Usually capsule: Usually liquid in capsule and is ingested by patient with liquid drink. Sometimes some patients can not swallow pills and can be administered in these rare cases, if facility is informed in advance, in liquid form.
