Thyroid Uptake Scan Thyroid Uptake Scan. A thyroid uptake scan helps to evaluate the overall function of the thyroid gland. Other names for thyroid uptake and scan include Thyroid scintiscan and Technetium thyroid scan. The thyroid uptake scan test makes use of a radioactive substance and a scanning device to assess the thyroid gland.

Thyroid Gland Function Tests Thyroid Scans are used for the following reasons: 1  Identifying nodules and determining if they are hot or cold. 2  Measuring the size of the goiter prior to treatment. 3  Follow-up of thyroid cancer patients after surgery.  Locating thyroid tissue outside the neck, i.e. base of the tongue or in the chest.

- In a thyroid scan doctors are generally looking at the size, shape and structure of the thyroid gland. A thyroid uptake test checks how well the gland is working. Both tests are based on the same principles and use the same equipment, just in slightly different ways.

Thyroid Scan A thyroid scan can show the size, shape, and location of the thyroid gland. It can also find areas of the thyroid gland that are overactive or underactive. The camera takes pictures of the thyroid gland from three different angles. The radioactive tracer used in this test is either iodine or technetium.A radioactive iodine uptake (RAIU) test may also be done to find problems with how the thyroid gland works, such as hyperthyroidism.

- Success of ablation was evaluated using a Thyrogen whole body scan and radioiodine uptake measurement taken eight months following ablation, and was based upon a primary endpoint of no visible thyroid bed uptake or, if visible, uptake less than 0.

Thyroid Scan and Uptake You will be given radioactive iodine (I-123 or I-131) in liquid or capsule form to swallow. The thyroid uptake will begin several hours to 24 hours later. Often, two separate uptake measurements are obtained at different times. For example, you may have uptake measurements at four to six hours and 24 hours.

Thyroid Tests A radioactive iodine uptake test, also called a thyroid uptake test, can help check thyroid function and find the cause of hyperthyroidism. The thyroid “takes up” iodine from the blood to make thyroid hormones, which is why this is called an uptake test.

Thyroid Scan For thyroid tests, radioactive iodine typically is used. Your thyroid and most types of thyroid cancer absorb iodine naturally. After the radioactive iodine accumulates in the thyroid tissue, the radioactive emissions can be detected by equipment outside the body, allowing your doctor to evaluate your thyroid function. A radioactive iodine uptake test (RAIU) test measures thyroid function without imaging. 2  A whole-body thyroid scan, or metastatic survey, is used to evaluate patients with thyroid cancer. 3  The scan evaluates the spread of thyroid cancer to other parts of your body.

Thyroid scan A thyroid scan is a nuclear medicine test that uses a radioactive iodine tracer to examine the structure and function of the thyroid gland. This test is often done together with a radioactive iodine uptake test.

Radioactive Iodine Treatment of Hyperthyroidism Therefore, the thyroid gland, which takes up iodine to make thyroid hormone, cannot distinguish between the two. However, the nucleus of a radioactive iodine molecule has excess energy and gives off radiation that can have effects on the cells in which it is concentrated.

Thyroid Scan and Uptake Thyroid scan and uptake uses small amounts of radioactive materials called radiotracers, a special camera and a computer to provide information about your thyroid’s size, shape, position and function that is often unattainable using other imaging procedures.

Radioactive Iodine for the Treatment of Thyroid Cancer Radioactive iodine treatment of thyroid cancer is not a new therapy and has been used for over 50 years. For a historical overview, see The beginnings of radioiodine therapy of metastatic thyroid carcinoma: a memoir of Samuel M. Seidlin, M. D. (1895-1955) and his celebrated patient.

Treatment of an Over-active or Enlarged Thyroid Gland with Radioactive Iodine Radioactive iodine (I-131) has been used to treat over-active thyroid disorders (hyperthyroidism) since the early 1940s. It is an effective method of treatment. It is now being used more often as a first-line treatment rather than surgery. Radioactive iodine is taken up by the thyroid, and destroys the cells in the thyroid gland, causing the gland to shrink, reducing the amount of thyroxine made by the thyroid gland.

thyroid ultrasound Thyroid ultrasound is an imaging technique used for diagnosing suspected thyroid disease. It uses harmless, high-frequency sound waves to form an image. The sound waves are reflected by thyroid tissue to form a picture of internal structures.he thyroid gland is an organ located in front of the neck. It plays an important role in controlling the body's metabolism. Most thyroid ultrasounds are performed to evaluate a small lump (nodule) in the thyroid found during a physical examination or found by a radionuclide study (thyroid scan).

Radioactive Iodine Uptake Testing In medicine, this radiation is used for diagnosis and treatment. A normal thyroid gland traps about 10-35 % of ingested radioiodine through the sodium-iodide symporter (NIS).NIS is also present in the salivary glands and breast, but only the thyroidal NIS is regulated by the thyroid-stimulating hormone (TSH).

- Nuclear imaging uses low doses of radioactive substances linked to compounds used by the body's cells or compounds that attach to tumor cells. Using special detection equipment, the radioactive substances can be traced in the body to see where and when they concentrate.

Radioactive iodine uptake Radioactive iodine uptake (RAIU) is a test of thyroid function. It measures how much radioactive iodine is taken up by the thyroid gland in a certain time period. A similar test is the thyroid scan. The two tests are commonly performed together.

Radioactive Iodine Treatment (RAI) Further information can be found on the Clinical Trials pages of this website. Like ordinary iodine in the diet, radioactive iodine is taken up by any remaining normal thyroid cells and potentially by thyroid cancer cells as well. The radioactive form of iodine is used to destroy any remaining thyroid cells.

- What radioactive iodine is. Radioactive iodine treatment is a type of internal radiotherapy. The treatment uses a radioactive form of iodine called iodine 131 (I-131). The radioactive iodine circulates throughout your body in your bloodstream. Thyroid cancer cells pick up the iodine wherever they are in your body.adioactive iodine treatment is a type of internal radiotherapy. The treatment uses a radioactive form of iodine called iodine 131 (I-131). The radioactive iodine circulates throughout your body in your bloodstream.

- Treatment Overview. Radioactive iodine, given in a capsule or liquid form, is absorbed and concentrated by the thyroid gland. The treatment destroys thyroid tissue but does not harm other tissue in the body. See a picture of the thyroid gland . While radiation can cause thyroid cancer, treatment of hyperthyroidism with radioactive iodine does not increase your chances of getting thyroid cancer.

Grey or Gray: Whatâs the Difference? When to Use Grey. Even though the only thing separating grey and gray is a dialectical difference, it is still important to keep the audience in mind while you are using these words. Grey (with an “E”) is the preferred choice in British English. If you find yourself writing to a British audience in an English newspaper or magazine, grey is the word choice you will want to use. As the above chart indicates, grey is much more preferred in British English.

FDG Uptake Explanation - PET SCAN RE: FDG Uptake Explanation - PET SCAN. uptake is the amount of radioactive sugar that the cells are using for metabolism. It is possible to have a positive area on PET that is not cancer. Thats why its important to compare one scan to the next to see if there are changes. This could be an increase in the number of areas that light up or an increase in activity in the same area. Since your moms have not changed, this would be a good sign.
