Question 1

if i had a thyroid scan that read: left lobe of gland is  mildly enlarged at 5.8cm x 1.7 x 2.2 .  there is a avascular 3 mm hypoechoic nodule in the lower pole of the left lobe. how would i know if it was " hot or cold"?

Accepted Answer

Different tests: You had a thyroid ultrasound which evaluates the anatomy of your thyroid gland. To find out if a thyroid nodule is hot or cold you need a nuclear thyroid scan aka i-123 uptake and scan. This latter is a functional test of your thyroid and characterizes nodules as hot, cold or warm (isointense). However, a 3 mm nodule is likely to small to characterize with a nuclear thyroid scan.

Question 2

what does a thyroid scan do?

Accepted 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:

Question 3

how expensive is it to get a thyroid scan?

Accepted Answer

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.

Question 4

what is the definition or description of: thyroid scan?

Accepted 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.

Question 5

what does a thyroid scan check for?

Accepted Answer

Goiter & cancer: A thyroid scan evaluates the size and consistency of the thyroid gland. The scan detects how some areas of the thyroid are working either more or less when compared to adjacent areas of the gland. This information is useful in assessing the presence of a goiter, a thyroid noduie or thyroid cancer.

Question 6

i'm due to have a thyroid scan in 3 days.  yesterday, i took two 25 mg antihistamine pills.  will this affect the results?

Accepted Answer

No, it should not.: The half life of most antihistamines should be less than 24 hrs and should be out of the system by then. I would check with the radiology center to confirm their policy. I would also avoid any more antihistamines until the time of testing.

Question 7

how is the thyroid scan performed?

Accepted Answer

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.

Question 8

what's the purpose of thyroid scan?

Accepted Answer

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.

Question 9

when getting a thyroid scan, what's the procedure?

Accepted Answer

Imaging  gland: 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.

Question 10

whats the low iodine diet for the thyroid scan?

Accepted 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.
