what does a thyroid scan do?

Thyroid scan

Thyroiditis
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.

Dr. Mike J. Bowman answered:

How is the thyroid scan performed?

2 types of "scans"

Radioactive
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.

What does a thyroid scan check for?

Different things

Thyroiditis
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.

Dr. Mazen Ghani answered:

What's the purpose of thyroid scan?

A thyroid scan

Thyroiditis
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.

How long does a thyroid scan test take?

Varies

Open-uri20120826-27145-qv7g46
A thyroid uptake and scan may be done with different isotopes and protocols resulting in scan time variation. Typically is done with I-123; you take the capsule one day and you come back the next day at 24 hr for a neck scan that takes aprox 15-20 minutes. In certain circumstances some places do this scan at 4-6 hours after you take the capsule.

How expensive is it to get a thyroid scan?

Depends

Thyroid_scan
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

What do i have to do before my thyroid scan?

If hyperthyroidism

Open-uri20120817-28614-qz2igj
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.

Dr. Peter Corrado answered:

What type of doctor can order a thyroid scan?

Many

Thyroid_scan
A thyroid scan gives info about metabolic activity in the thyroid gland. Almost any doctor involved in general medical care would be able to order this test if the patients history or physical findings supported the need. Depending on test results you may require follow up with an endocrinologist or a surgeon.

Whats the low iodine diet for the thyroid scan?

Preparation

Open-uri20120820-16692-17jdpi
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

What should I have to do after my thyroid scan?

Resume daily life

Thyroid_scan
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.
