Do You Need To Be Npo Before A Thyroid Scan
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
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.

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
Varies: 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. ...Read moreSee 2 more doctor answers
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 2 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 scan..: There are two types of nuclear thyroid scan. One involves IV injection of a tracer. The other involves ingestion of a radioactive iodine pill. The pill is more common....Usually you will be told not to consume foods with high iodine content for a few days before scan. 1st day you ingest the pill and you come back the next day for images of the neck on a gamma camera and calculation of uptake. ...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
