Thyroid Scan And Uptake Results
The patient ingests radioactive iodine or has intravenous injection of radiotracer technetium to define structure, size, and function of thyroid gland. Overactive (hyperthyroid) normal, and underactive thyroid glands are determined. Sometimes autoimmune conditions and tumors of the gland can be suspected. Correlative imaging ultrasound, mr imaging, and blood tests ...Read more
One after the other: The exact scanning time after taking the capsule varies according to the isotope and protocol used. For i-123 and low i-131 the uptake and the scan is usually done at 24 hours. A thyroid probe directed to your neck measures the radioiodine uptake, this is follow by a gamma camera scan which makes an image of your thyroid gland based on the radioiodine distribution. ...Read moreSee 2 more doctor answers
Single hot 1 CM nodule on thyroid scan with normal thyroid blood panels & uptake. Chances of malignancy?
Not likely: "hot" nodules are rarely cancer and most often represent benign follicular adenomas. These are also known as "autonomous" nodules because they make thyroid hormone but don't respond to the body's normal signals telling them when to stop making the hormone. The vast majority of thyroid cancer nodules are "cold" on a thyroid scan. ...Read more
Just got the results of thyroid scan. The range is 5% to 30% in 24hrs. Mine's is 64% first day, 70% second day and 64.8% for the last day. Help!?
Hyperthyroidism: Your values of thyroid uptake are increased indicative of probable graves disease or hyperthyroidism especially if scan showed homogeneous enlarged thyroid. Sometimes oral medication is used to control hyperthyroidism. Sometimes medical therapy does not maintain control of disease. Some people have radioactive ablation of thyroid with i131which destroys gland, patient takes daily hormone supplements. ...Read moreSee 2 more doctor answers
I'm due to have a thyroid scan in 3 days. Yesterday, I took two 25 mg antihistamine pills. Will this affect the results?
It means: You have multiple fluid-filled of minimally cellular nodules and cysts, which are present in approx 50% of healthy normal individuals. Discuss the full findings with your doctor. ...Read more
Need more info: Not sure what you mean by "test results" but u cannot know that u have multinodular goiter from a blood test. A thyroid ultrasound can give u this diagnosis in which case u will need a blood test called TSH to know what to do next. No thyroid scan needed unless the TSH is low. Thyroid ultrasound vs. Biopsy might be needed depends on the size and characteristics of the nodules but need more info. ...Read moreSee 2 more doctor answers
I had a radioactive thyroid scan. The results show an overproducing thyroid, with a pyramidal lobe, but my TSH came back at 4.3.What could it be?
I had a radioactive thyroid scan. The results show an overproducing thyroid, with a pyramidal lobe, but my TSH came back at 4.3.Endocronologist next?
Likely Hashimoto's: You cant tell anything about thyroid function based on a thyroid scan. This is a common mistake made by radiologists. All you can assess is how much iodine is taken up by the thyroid gland and how it appears, not how much thyroid hormone is being produced. Your TSH is borderline elevated. The most likely cause for these findings in your age group is Hashimoto's thyroiditis. Seeing an endo is good ...Read more
Thyroid scan/uptake shows mild hyperthyroidism, blood-work shows hypothyroidism. What's up with that?
Labs are right: Thyroid scan/uptake shows how active someone's thyroid is in trapping iodine, but not whether or not their thyroid is able to convert iodide to iodine and make thyroid hormone with it. In this situation, the labs tell the true story - that the thyroid can't make enough thyroid hormone. Uptakes and scans are morehelpful in people with hyperthyroidism, and don't add much info in hypothyroidism. ...Read moreSee 1 more doctor answer
My thyroid scan/uptake shows mild hyperthyroidism, but blood-work shows hypothyroidism. Does this happen often? What should I do?
Antibodies: You probably have several types of thyroid antibodies floating around your system. Some cause hyperthyroidism while others may block their effect on the thyroid receptor. Treat your levels- if you're hypo - treat with synthroid (thyroxine). Monitor function and antibody levels over time. ...Read moreSee 1 more doctor answer
Thyroid scan: It's a nuclear medicine scan use to evaluate how well your thyroid is working. The result will give information on the size, shape, location and the overall activity of the gland. It can also tell you if a thyroid nodule is functioning or non-functioning and help your doctor determine whether a nodule biopsy is needed. More info with the link below: http://www. Webmd.

Depends: Usually this is covered by your insurance. If you get a radioiodine thyroid scan it will be more expensive than a tc99m pertechnetate scan. Are you getting a scan alone or scan plus uptake? That will affect costs. I am estimating that you are looking at costs in the range of a hundred to several hundred dollars but these costs are generally set by the administration / management and not physician. ...Read moreSee 1 more doctor answer
If hyperthyroidism: If you are having a diagnostic dose of i-123 (usually 200 microci), you should stop taking anti-thyroid medications (methimazole and ptu) and make sure you didn't have iodine-based IV contrast (used in ct scans) in the prior 6-8 weeks. For a diagnostic study a low-iodine diet is not require, unless you are going to received i-131 treatment shortly after the test. ...Read moreSee 3 more doctor answers
Resume daily life: If thyroid scan was performed with iodine 123 or technetium 99m pertechnetate involves a low amount of radiation. The half lives are short enough (13 and 6 hours) that most irradiation will have dissipated by 24-48 hours. Whatever i123 does not accumulate in thyroid gland are excreted via kidneys, saliva, and sweat. Tc 99m usually exits via kidneys, GI tract, and saliva. I131 involves higher dose. ...Read moreSee 1 more doctor answer
Thyroid function: The patient ingests radioactive iodine or has intravenous injection of radiotracer technetium to define structure, size, and function of thyroid gland. Overactive (hyperthyroid) normal, and underactive thyroid glands are determined. Sometimes autoimmune conditions and tumors of the gland can be suspected. Correlative imaging ultrasound, mr imaging, and blood tests are used for confirmation. ...Read moreSee 2 more doctor answers
Different things: We use thyroid scans to help distinguish between functioning and non-functioning thyroid nodules, to assess activity of the thyroid for purposes of ablation in cases of grave's disease, to follow up patients who've had their thyroid glands removed because of cancer. ...Read moreSee 1 more doctor answer
Preparation: Some diagnostic centers ask patients to undergo a 2 week low-iodine diet prior to a thyroid uptake and scan. This is because the study uses radioactive iodine (i-123 or low i-131) for the test. The iodine contained in food (seafood, table salt, etc.) may compete with the iodine used for the study, and thus results may be biased. Ideally, for the study your thyroid gland should be "hungry" for iodine. ...Read moreSee 2 more doctor answers
2 types of "scans": Thyroid ultrasounds are quick and painless. They are done with some jelly on the neck and sound waves are used to visualize the thyroid and surrounding tissues. Nuclear medicine scans are done by swallowing a small amount of radioactive iodine. After some time, the iodine finds its way to thyroid tissue and "lights up" on the scan. This is painless, safe, but does take a while. Best wishes. ...Read moreSee 2 more doctor answers
A thyroid scan: Uses a radioactive tracer and a special camera to measure how much tracer the thyroid gland absorbs from the blood. A thyroid scan can show the size, shape, and location of the thyroid gland. It also finds areas that are overactive or underactive and to evaluate possible masses that may be felt or seen with ultrasound. ...Read moreSee 2 more doctor answers
