The Radioactive Iodine Uptake Of The Thyroid Gland

The radioactive form of an element acts in the same way the nonradioactive form does. When a person ingests iodine it concentrates in the thyroid gland whether it is in a radioactive or nonradioactive

The iodine uptake with hyperthyroidism is greater than normal. This means that the body produces too much thyroid, meaning there is too much

Hypothyroidism, while a common disorder, is often misdiagnosed due to its ability to mimic other common health problems. A simple, yet specialized blood test, coupled with a complete medical history, will allow the experts at RCMC Medical Center to not only diagnose the problem in a timely manner, but also develop a treatment plan based on the results, and your personal lifestyle, with the end goal of returning you to the level of health and wellness you

Week 3 – LOM Assignment The thyroid is responsible for taking iodine and converting it into thyroid hormones which are released into the blood stream and transported throughout the body where they control metabolism.1 The thyroid is a vital part of the human body as every cell in the body depends on it for metabolic regulation. Too much or too little thyroid hormone secretion can result in hyperthyroidism or hypothyroidism. Hyperthyroidism is caused when the thyroid secretes too many thyroid hormones. Hyperthyroidism causes a rapid heart rate, elevated blood pressure and tremors. Other symptoms include increased nervousness, inability to concentrate, weakness, restlessness, difficulty sleeping, frequent bowel movements, weight loss and irregular

Doctors use Iodine-131. Iodine-131 can be used to treat someone with hyperthyroidism. It can also be used to treat thyroid cancer. It can also be used as a type of medical imaging.

* Radioactive iodine to destroy thyroid tissue and lower the amount of hormone being produced

The health care provider ordered blood work that included thyroid-stimulating hormone, triiodothyronine, thyroxine, and radioactive iodine uptake to confirm the diagnosis of hyperthyroidism. The labs returned with an elevated level of triiodothyronine and thyroxine, while the thyroid-stimulating hormone was decreased. There was also an

Graves’ disease is often associated with the over activity of the thyroid gland, also known as hyperthyroidism. It is more common among women, and

The patient’s diagnosis is primary overt hypothyroidism. The patient presents with certain features such as weight gain, weakness, excessively dry flaking skin, dry hair, sluggish movements, constipation, bradycardia, diminished deep tendon reflexes, and bilateral edematous hands, which is classical signs and symptoms for primary hypothyroidism. The patient laboratory test reveals she has an elevation in serum thyroid stimulating hormone level along with low serum free thyroxin and triiodthyronine levels, which indicates it is a dysfunction or abnormality in the thyroid gland as opposed to the pituitary gland or hypothalamus (Gaitonde; Lohano; Porth, 2015, p. 780; Ross, 2014).

We also get iodine from the food we eat. Iodine can become dangerous when we don't eat enough of it and too much. Iodine deficiency will slow down the thyroid function and cause it to swell up. Too much iodine can affect the whole body. Loss of weight and disturbed heartbeats can occur.Iodine minerals are very rare. Salt solutions often contain a little iodine and 0.3% of iodine can be contained in sodium and calcium nitrate deposits. It can also be extracted from seaweed.It can melt at 113.5°C and boil at 184°C. It dissolves only slightly in water, but other liquids can give it a higher solubility.One of the first commercial uses for Iodine was for Photography. It was used in a technique for producing images on a piece of metal. These images were called daguerreotypes. As well as photographic chemicals, iodine now has many more uses. Iodine salts are used in pharmaceuticals and disinfectants, printing inks and dyes and animal feed supplements. It is also used to make polarising filters for LCD displays.Iodine is also added in small amounts to table salt, to avoid iodine deficiency. The radioactive isotope (iodine 131) is sometimes used to treat cancerous thyroid

The most commonly used radio tracer for thyroid imaging are TC99m(pertechnetate) , iodine-123 and iodine-131. Thyroid evaluation is one of the most frequently performed nuclear medicine procedure.The equipment use to test for the radioactivity is the gamma probe and is the only device used to test for graves disease. (*3)This device is a handheld device with a Geiger-muller tube, or or scintillation counter, for intraoperative use following interstitial injection of a radionuclide, to locate regional lymph nodes by their radioactivity It is used primarily for sentinel lymph node mapping and parathyroid surgery. The Gamma Probe is also used for RSL (Radioactive Seed Localization), to locate small and non-palpable breast lesions. The sentinel node market experienced high growth in the early and mid 90's starting with melanoma sentinel node surgical search and breast cancer sentinel node staging; both are currently considered standards of care. Most surgeons propose node staging after a positive breast biopsy. New applications are being developed for parathyroid direct detection and intra-operative detection of cancerous tissue using tumor-seeking radiopharmaceuticals. Parathyroid detection is growing fast, while the intraoperative use of gamma probes for direct tumor detection is just emerging. Canberra is one of the manufactures of a gamma probe also know as a GP series- Geiger muller detractors A gamma probe is A pair of rugged halogen-quenched GM detectors serves as the basic detection elements in the GP Series detectors used for wide range gamma radiation measurement. The way this device works is the signal from the gamma probe with Geiger-muller tube and the voltage power supply go to the preamplifier to another amplifier and threshold control. This signal is split one side goes to the rate meter and audio circuit, the other signal goes to the scaler and display driver circuitry which is

The main cause of hyperthyroidism Graves’ disease which affects quite a few people in the general population. This disease is characterized as an autoimmune disorder. This means that the body makes antibodies known as thyroid stimulating immunoglobulin that bind and over activate the production of thyroid hormones [3]. So in essence the antibody mimics the thyroid stimulating hormone and when the negative feedback loop is in affect the antibody still binds to the thyroid and T3 and T4 are over produced [2].

Iodine 123 is a substance that is used to see where any thyroid tumours are in the body. Both thyroid cancer and thyroid tissue trap iodine. This helps us find where there is active thyroid cancer. This procedure is called a diagnostic thyroid cancer survey. If thyroid cancer is found during your survey, you may have it treated with a dose of a radioactive iodine called Iodine 131. This is called a therapeutic dose.

One of the way to treat hyperthyroidism is to damage or destroy the thyroid cells that make thyroid hormone. Because these cells need iodine to make thyroid hormone, they will take up any form of iodine in the blood stream, whether it is radioactive or not. The radioactive iodine used in this treatment is administered by mouth, usually take about 1 GBq of 131I( IAEA, VIENNA, 1996).Once swallowed, the radioactive iodine gets into your bloodstream and quickly is taken up by the overactive thyroid cells. The radioactive iodine that is not taken up by the thyroid cells disappears from the body within days. Over a

Pregnant women are putting their unborn baby at risk and themselves, studies have concluded that low levels of iodine
