Thyroid Uptake and Scan
* Inform your physician if you are pregnant or breast feeding.
You have been scheduled for a Thyroid Uptake study which involves the use of a small amount of radioactive material. The level of radioactivity used is extremely low and has no side effects.
You will be positioned on an imaging table, under a special detector called a gamma camera. The camera does not produce any radiation. It will be placed close to the part of your body being imaged.
Patient Preparation
Stop all thyroid medications. Your physician will advise you.
No I.V. contrast agents for 30 days prior to test.
Procedure
This is a 3 part study. On your first visit, you have measurements of your thyroid gland taken with a radiation sensitive probe, then you will be given a small amount of radioactive material to drink. A small amount of a different radioactive substance will be injected into a vein in your arm, as well. On your second visit (15 minutes later), painless images will be obtained for approximately 45 minutes. On your third visit (24 hours later), a measurement of your thyroid gland will be taken. This takes 15 minutes.
