Thyroid Ultrasound Thyroid ultrasound refers to the use of high frequency sound waves to obtain an image of the thyroid gland and identify nodules. It tells if a nodule is "solid" or a fluid-filled cyst, but it will not tell if a nod.
I have another consult next week with another endo and won't stop until I find one willing to listen to me. You have given great advice as far as what to ask for and discuss with the next endo.

CTS of the normal thyroid gland In addition to making thyroid diagnosis more accurate, the CRT scanner improves the results of thyroid biopsy. The accurate sizing of the thyroid gland aids in the follow-up of nodules to see if they are growing or getting smaller in size.

I'm making notes and going in a little better prepared this time. I have to admit to being terribly afraid at this point. I had a very bad day today. I was able to do things around the house that I haven't been able to do in nearly a week but the energy I had.
Modern measurement of thyroid hormones is done by a new technique, radioimmunoassay (RIA discovered by Dr. Solomon Berson and Dr. Rosalyn Yallow. They were awarded the 1977 Nobel Prize in Medicine for this discovery which revolutionized the study of thyroid disease as well as the entire field of endocrinology.
Hypothyroid patients usually take up too little iodine and hyperthyroid patients take up too much iodine. The test is performed by giving a dose of radioactive iodine on an empty stomach.
If the T4 level is low and TSH is not elevated, the pituitary gland is more likely to be the cause for the hypothyroidism. Of course, this would drastically effect the treatment since the pituitary gland also regulates the body's other glands (adrenals, ovaries, and testicles) as well as controlling growth in children and normal.
The following are commonly used thyroid tests. Measurement of Serum Thyroid Hormones: T4 by RIA. T4 by RIA (radioimmunoassay) is the most used thyroid test of all. It is frequently referred to as a T7 which means that a resin T3 uptake (RT3u) has been done to correct for certain medications such as birth control.

What do I know though, I'm just the person suffering the horrendous symptoms?!?! Thank you so much for your input. My mind kept coming back to Grave's Disease based on what I have been reading.

Therefore, it is usually done at the same time that the iodine uptake test is performed. Although other isotopes, such as technetium, will be concentrated by the thyroid gland; these isotopes will not measure iodine uptake which is what we really want to know because the production of thyroid hormone is dependent upon absorbing iodine.
My guess is that your doctor should next check for Graves antibodies (especially) and TPO and Thyroglobulin antibodies, as well as taking real Free T4, Free T3 and TSH readings. Those labs woudl tell us what your thyroid levels look like, what your body THINKS thyroid levels should be, and whether antibodies are attacking your.
