This is a test to look at the size, shape, position and activity levels of the thyroid gland. You will be given an injection in your arm of a small amount of radioactivity that settles in the thyroid tisssue. This feels very similar to a blood test and has no side effects.

Images of the thyroid are taken immediately on a gamma camera. You do not need to undress but may be asked to remove any large necklaces.

After the images are completed, the technologist will check them and you will be able to go home. A written report will be sent to the referring doctor unless you have a clinic appointment within our department on the same day. There are no side effects from the test.
