Glossary -   Thyroid uptake and scan



This is an imaging test that looks at the structure and function of the thyroid gland. It can show whether the thyroid is in the normal place, has a normal size and whether it is working correctly. The scan is done by injecting a small amount of radioactive material into a vein or having the patient swallow it by mouth. The material collects in the thyroid gland so an imaging machine can create a picture of the thyroid.
