I 123 Uptake and Thyroid Scan
A thyroid uptake and scan is a special test that uses a radioactive substance (or tracer) to examine how the thyroid gland looks and how it works.
A thyroid uptake and scan is performed to determine size, structure and function of the thyroid gland.
Before the procedure
Before the examination, you should tell your physician if you are pregnant or nursing. Your physician may instruct you not to take certain thyroid medications, as they will interfere with the test results. You should tell your physician and the technologist performing the exam if you are taking any herbal supplements, as they may also affect the test results. Do not eat or drink for two hours prior to receiving the I 123 capsule(s) and for two hours after receiving the capsule.
During the procedure
This test is done in 2 parts on 2 separate days. On the first day, you will be asked to swallow a small amount of radioactive iodine (or tracer) in capsule form. There are no side effects from the capsule. The thyroid gland absorbs iodine and will absorb the radioactive tracerThe first day visit will take about 15 minutes. The next day you will return for the scan and uptake procedures. You will be positioned on a table on your back. The camera will be positioned close to your face and neck and will acquire three pictures. Each picture can take as long as 10-15 minutes. Total length of second day visit is about 30-45 minutes.
After the procedure
Your doctor will be contacted with the results of your test and will discuss the results with you.
