Thyroid Scan

What is a Thyroid Scan?

A Thyroid Scan is performed to evaluate thyroid nodules and diagnose hyperthyroidism or hypothyroidism.

What takes place during the test?

A Thyroid Scan takes place over a two day period. Day one you will receive 2 capsules containing radioactive iodine. You should experience no ill side effects from the dose. Additionally, the radioactive material is harmless to you or anyone you come into contact. Due to the iodine content within seafood, you should refrain from eating any seafood following the dose until the scan is completed. You will return the following day (day 2) within 24 - 36 hours of the day one dose for the scan of the thyroid area lasting approximately 1 1/2 hours. During the scan, you will lie on the imaging table with the camera positioned above or below you while several images are taken.

How long will the test take to complete?

Day dose one will take approximately 10 minutes followed by a 24 hour delay and a 1 1/2 hour scan.
