Thyroid Uptake and Scan

A thyroid uptake and scan (or thyroid scan only) is a procedure that evaluates thyroid nodules, hyperthyroidism, hypothyroidism and a goiter.

The thyroid uptake portion evaluates your thyroid function.

What to Bring

  • Your medical provider order (Your medical provider may have already sent this to us.)
  • Personal ID
  • Insurance card(s)
  • Medication list

How to Prepare

  • You cannot have any iodinated contrast media for 6 weeks (CT, EXU, or angiograms) before the exam.
  • You cannot take myelogram for 6 months before the exam.
  • Ask your medical provider about discontinuing thyroid and anti-thyroid medications for 2 weeks before your exam.
  • Refrain from eating kelp, sushi and seaweed for 1 week before the exam.
  • Please do not eat or drink 2 hours before the exam.
  • Please inform the technologist if you are pregnant or think you might be pregnant.
  • If you wear an on-body device (insulin pump, insulin regulators, Neulasta, other chemo/insulin devices, etc.), you must inform your technologist.

What to Expect

  • Upon arrival, the technologist will explain the procedure and answer any questions you might have.
  • You will be given a small capsule (to swallow) containing a tiny amount of radioactive material and will then be asked to not eat for 2 hours. This is to ensure maximum absorption of the capsule.
  • You will be asked to return approximately 6 hours later for 30 minutes of imaging.
  • Depending on your medical provider’s order, you may also return the following morning for 5 minutes of imaging.

During the Exam

  • You will be lying down on a cushioned table.
  • A camera will be placed over your neck.

After the Exam

  • You may resume your thyroid medications as prescribed.
