I've done a thyroid u/s. Dr. Called and said they found 2 thyroid nodules. Now i'm going for a thyroid uptake scan. What will this test do or show?
Hot or cold: Thyroid nuclear scan usually with iodine 123 will show whether nodule is active (hot, increased uptake, or nonactive (cold, decreased uptake).More cold nodules are cancer.For patients presenting with thyroid nodules greater than 1 cm. In diameter (up to 20% will be malignant). They should be carefully evaluated, and managed. If greater than 1 cm. Should be closely followed or biopsied. ...Read moreSee 2 more doctor answers
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
YES: An uptake value will be established. Uptake can be low, normal, or high. Scan will be diagnostic if enough iodine localizes in the thyroid gland. Large amounts of stable iodine from iodized salt and ocean seafood can compete with radiodine and decrease uptake. ...Read moreSee 2 more doctor answers

I'm in the process of taking a radioactive iodine pill for a 1-123 thyroid uptake scan, will smoking pot affect the results?
One or two days: The thyroid scan can be performed either with iodine 123 or iodine 131. The scan itself is very rapid ( approximately 10 minutes). According to the type of radioiodine used, it is faster ( same day) with 123iodine or we need to wait 24 hours in the case of 131 iodine. Usually the thyroid uptake is performed with 131 iodine and the thyroid scan is performed with 99mtc-pertechnetate ...Read moreSee 2 more doctor answers
If i don't have graves' disease and my thyroid uptake scan is as follows: range-5% to 30% my readings- 64%, 70%, 65%. What is my best course?
Hyperactive thyroid: Thyroid uptake in range of 64% to 70% usually means overactive thyroid. Graves disease or hyperthyroidism is one cause. An overactive thyroid nodule, thyroiditis, and toxic multi nodular goiter can be other causes. An adenoma of the pituitary gland can sometimes stimulate overproduction of thyroid hormone. Clinical examination, nuclear and/or ultrasound imaging, and various blood tests can help. ...Read moreSee 2 more doctor answers
TSH is constantly suppressed.FT3 borderline high. FT4 borderline low. Tested 5 times. Thyroid uptake scan = *low 5.3% wo nodules. Please help explain.
Thyroiditis: Why are you having your thyroid tested? what are your symptoms? start from the begining. Medicine is not about scans and numbers. TSH is suppressed by the elevated T3 (liothyronine) as feedback inhibition. I would expect normal to high uptake but it can be low in some cases of Hashimoto's thyroiditis. thyroid scan in Hashimoto's thyroiditis can mimic a wide range of thyroid disorders. Thyroid may be burning out. ...Read more
