Radioactive Iodine Uptake Side Effects
Radioactivity refers to the particles which are emitted from nuclei as a result of nuclear instability. Because the nucleus experiences the intense conflict between the two strongest forces in nature, it should not be surprising that there are many nuclear isotopes which are unstable and emit some kind of radiation. The most common types of radiation are called alpha, ...Read more
Radioactive iodine uptake test - can I still travel afterwards or would I have to hide out for a few days?
It will not: An i131 test does not "diagnose" goiter. Goiter is just a term meaning an enlarged and/or nodular thyroid. An i131 scan is a "fucntional" scan. It is used to determine if a nodule within the thyroid is "hot" - picks up a lot of iodine: hyper-metabolic. A "cold" nodule does not concentrate the iodine: hypometabolic. There is a lower risk of thyroid cancer in "hot" nodules. ...Read moreSee 1 more doctor answer
Radioactive iodine uptake scan, should I go to work after? Am a food service clerk. How long should I stay away from pregnant daughter and toddler .
Only scan and uptake: Hi. If all you had was scan and uptakes, you don't have to stay away from anyone or anything. The isotope used for scan and uptakes is 123-I, and is completely harmless to your thyroid (or anyone else's). If you were treated with 131-I after the scan and uptakes, that isotope is harmful to the thyroid, but doesn't come out of your skin! You can work and be around others. It comes out in your urine ...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?
I had a partial thyroidectomy and the radioactive iodine treatment for the other side due to goiter-nodule with small cancer. Synthroid (thyroxine) reduced-why?
For RAI to Work: The overall treatment is a little confusing as cancer is usually surgically removed, but there are a few reasons to lower your Synthroid (thyroxine). It may be held for a while so your left over thyroid tries to work and will suck up the RAI. The other reason is when the thyroid cells die they will release thyroid hormone. This could temp make you hyperthyroid. Eventually your dose will be adjusted again. ...Read moreSee 1 more doctor answer
