What isotope would be best to study the thyroid gland?
Radioactive Iodine (I-131) Therapy for Hypothyroidism
Radioiodine therapy is a nuclear medicine handling. Doctors use it to treat an overactive thyroid, a condition called hyperthyroidism. They also may use it to treat thyroid cancer. When a small dose of radioactive iodine I-131 (an isotope of iodine that emits radiation) is swallowed, it is captivated into the bloodstream. The isotope is concentrated by the thyroid gland, where it begins destroying the gland'southward cells.
Your doctor volition instruct you lot on how to prepare, how to take any necessary radiation safety precautions, and when to cease taking anti-thyroid medications. Tell your doc if there's a possibility you are pregnant or if you are breastfeeding. Discuss any recent illnesses, medical conditions, allergies, and medications you lot're taking. This procedure requires petty to no special preparation. However, you should not eat or drink anything after midnight on the day of treatment.

What is Radioiodine (I -131) Therapy and how is it used?
Radioactive Iodine I-131 (as well called Radioiodine I-131) therapy is a nuclear medicine treatment. Doctors use it to treat an overactive thyroid, a status chosen hyperthyroidism. Hyperthyroidism can be caused past Graves' disease, in which the unabridged thyroid gland is overactive, or by nodules within the gland which are locally overactive in producing too much thyroid hormone.
Nuclear medicine uses pocket-sized amounts ofradioactivematerial chosen radiotracers. Doctors employ nuclear medicine to diagnose, evaluate, and care for various diseases. These include cancer, heart disease, gastrointestinal, endocrine, or neurological disorders, and other conditions. Nuclear medicine exams pinpoint molecular activity. This gives them the potential to find disease in its earliest stages. They can as well show whether yous are responding to treatment.
The thyroid is a gland in the neck that produces two hormones. These hormones regulate all aspects of the body'south metabolism, the chemical procedure of converting food into energy. When a thyroid gland is overactive, it produces besides much of these hormones, accelerating the metabolism.
Radioactive iodine (I-131), an isotope of iodine that emits radiation, is used for medical purposes. When a small dose of I-131 is swallowed, information technology is absorbed into the bloodstream in the gastrointestinal (GI) tract. It is concentrated from the claret by the thyroid gland, where it begins destroying the gland's cells.
Doctors as well employ radioactive iodine I-131 to treat thyroid cancer.

Who volition exist involved in this process?
A radiologist who has specialized training in nuclear medicine and others, perhaps including an endocrinologist, thyroid surgeon, and radiation rubber officeholder, will exist part of your handling team.

What equipment is used?
In that location is no equipment used during radioactive iodine therapy.

Who operates the equipment?
There is no equipment used during radioactive iodine therapy, the patient simply swallows a prepared dose.

Is at that place whatever special training needed for the procedure?
Y'all should not eat or potable later midnight on the day of the procedure. If you have been taking anti-thyroid medications, you must stop at least three days earlier the therapy is given. Frequently, your md will recommend stopping anti-thyroid medication for five to seven days before therapy.
You will be able to render home following radioactive iodine handling. Even so, you should avoid prolonged, shut contact with other people for several days, especially significant women and pocket-size children. Almost of the radioactive iodine that has non been captivated leaves the body during the first two days following the handling, primarily through the urine. Small-scale amounts volition likewise be excreted in saliva, sweat, tears, vaginal secretions, and carrion.
If your work or daily activities involve prolonged contact with small children or significant women, you should wait several days after your handling to resume these activities. Patients with infants at home should arrange for care to be provided by another person for the outset several days after treatment. Your radiologist can be more than specific for your given situation, but this is usually for two to five days.
Your treatment team will requite you a listing of other precautions to take following your handling with I-131. The post-obit guidelines comply with the Nuclear Regulatory Commission:
- Use individual toilet facilities, if possible, and flush twice after each utilize.
- Bathe daily and launder hands frequently.
- Drink a normal corporeality of fluids.
- Use disposable eating utensils or wash your utensils separately from others.
- Sleep alone and avoid prolonged intimate contact for 3 or four days. Cursory periods of shut contact, such every bit handshaking and hugging, are permitted.
- Wash your linens, towels, and wearing apparel daily at domicile, separately. No special cleaning of the washing machine is required betwixt loads.
- Exercise not prepare nutrient for others that requires prolonged handling with blank hands.
- If you are breastfeeding, you lot must stop several days before to ensure that milk production has likewise stopped.
- Yous should avert becoming pregnant from six months to one year after handling.
- You lot must be sure you are not pregnant before receiving I-131. Many facilities crave a pregnancy exam within 24 hours prior to giving I-131 in all women of child-bearing age who have not had a surgical process to prevent pregnancy.
Patients who need to travel immediately after radioactive iodine treatment are advised to carry a letter of the alphabet of caption from their physician. Radiation detection devices used at airports and federal buildings may exist sensitive to the radiation levels present in patients up to three months following handling with I-131. Depending on the amount of radioactivity administered, your endocrinologist or radiation condom officeholder may recommend continued precautions for up to several weeks after treatment.
Doctors do not apply radioiodine therapy in meaning patients. Depending on the stage of pregnancy, I-131 given to the mother may impairment the babe's thyroid gland. If you are pregnant, discuss this issue with your dr.. When given to a nursing mother, radioactive iodine can accomplish a babe through her breast milk. About physicians feel that this procedure should not be used in women who are breastfeeding unless they are willing to terminate breastfeeding. As well, you should avoid getting significant for at least vi to 12 months subsequently treatment.
Pre-menopausal women should fully discuss the use of I-131 with their doctor.

How is the procedure performed?
Hyperthyroidism handling is almost always done on an outpatient basis because the dose required is relatively small.
The radioiodine I-131 is swallowed in a single capsule or liquid dose and is quickly absorbed into the bloodstream in the gastrointestinal (GI) tract. It is concentrated from the blood by the thyroid gland, where it begins destroying the gland'south cells. Although the radioactivity remains in the thyroid for some time, information technology is greatly macerated within a few days. The consequence of this treatment on the thyroid gland usually takes betwixt one and 3 months to develop. Maximum do good occurs iii to six months afterwards treatment. Unremarkably, a single dose is successful in treating hyperthyroidism. However, rarely, a 2nd handling is necessary. A 3rd treatment is very rarely necessary.

What will I feel during this process?
Patients may experience pain in the thyroid after therapy like a sore throat. Ask your md to recommend an over-the-counter pain reliever if this occurs.
peak of page
Are there permanent side effects from the process?
Information technology is highly probable that this process will destroy some or nigh of your thyroid gland. Since hormones produced by the thyroid are essential for metabolism, virtually patients will need to take thyroid pills for the rest of their life following the procedure. Thyroid pills are inexpensive, and patients volition typically be prescribed one pill per day. There are essentially no other permanent side furnishings from the process. The risk of cancer from this therapy is very pocket-size.
