Thyroid Scan And Uptake Results
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
One after the other: The exact scanning time after taking the capsule varies according to the isotope and protocol used. For i-123 and low i-131 the uptake and the scan is usually done at 24 hours. A thyroid probe directed to your neck measures the radioiodine uptake, this is follow by a gamma camera scan which makes an image of your thyroid gland based on the radioiodine distribution. ...Read moreSee 2 more doctor answers
Single hot 1 CM nodule on thyroid scan with normal thyroid blood panels & uptake. Chances of malignancy?
Not likely: "hot" nodules are rarely cancer and most often represent benign follicular adenomas. These are also known as "autonomous" nodules because they make thyroid hormone but don't respond to the body's normal signals telling them when to stop making the hormone. The vast majority of thyroid cancer nodules are "cold" on a thyroid scan. ...Read more

Hyperthyroidism: Your values of thyroid uptake are increased indicative of probable graves disease or hyperthyroidism especially if scan showed homogeneous enlarged thyroid.Sometimes oral medication is used to control hyperthyroidism.Sometimes medical therapy does not maintain control of disease. Some people have radioactive ablation of thyroid with i131which destroys gland, patient takes daily hormone supplements. ...Read moreSee 2 more doctor answers

Need more info: Not sure what you mean by "test results" but u cannot know that u have multinodular goiter from a blood test. A thyroid ultrasound can give u this diagnosis in which case u will need a blood test called TSH to know what to do next. No thyroid scan needed unless the TSH is low. Thyroid ultrasound vs. Biopsy might be needed depends on the size and characteristics of the nodules but need more info. ...Read moreSee 2 more doctor answers
I had a radioactive thyroid scan.The results show an overproducing thyroid, with a pyramidal lobe, but my TSH came back at 4.3.What could it be?
I had a radioactive thyroid scan. The results show an overproducing thyroid, with a pyramidal lobe, but my TSH came back at 4.3.Endocronologist next?
Likely Hashimoto's: You cant tell anything about thyroid function based on a thyroid scan. This is a common mistake made by radiologists. All you can assess is how much iodine is taken up by the thyroid gland and how it appears, not how much thyroid hormone is being produced. Your TSH is borderline elevated. The most likely cause for these findings in your age group is Hashimoto's thyroiditis. Seeing an endo is good ...Read more
Thyroid scan/uptake shows mild hyperthyroidism, blood-work shows hypothyroidism. What's up with that?
Labs are right: Thyroid scan/uptake shows how active someone's thyroid is in trapping iodine, but not whether or not their thyroid is able to convert iodide to iodine and make thyroid hormone with it. In this situation, the labs tell the true story - that the thyroid can't make enough thyroid hormone. Uptakes and scans are morehelpful in people with hyperthyroidism, and don't add much info in hypothyroidism. ...Read moreSee 1 more doctor answer
