Thyroid Uptake and Scan

Your doctor has ordered a thyroid uptake and scan. The role of this procedure is to evaluate thyroid nodules, hyperthyroidism, hypothyroidism and goiter. Our team of specialized doctors, nurses and technologists is led by Alan Waxman, MD, Chief of Nuclear Medicine. This exam requires three visits over two days.

Why Choose the S. Mark Taper Foundation Imaging Center for a Thyroid Uptake and Scan?

Before Your Exam

You can print and fill out the Thyroid Diagnostic Intake Form before arriving to speed registration.

No iodinated contrast material for 6 weeks (CT, IVP or angio) before exam.

Ask your doctor about discontinuing Synthroid®, Levoxyl® or Levothyroxine® 6 weeks before exam, Cytomel® (T3) or Liothyronine 2 weeks before exam, and antithyroid medication 5 days before exam.

Avoid eating sushi, seaweed, kelp products or seafood 1 week before exam.You must discontinue thyroid hormones for 6 weeks before your exam.

We want to make your waiting time as pleasant as possible. Consider bringing your favorite magazine, book or music player to help you pass the time.

During Your Exam

Upon arrival, the technologist will explain your procedure and answer any questions you may have.

You will visit the department three times.

On your first visit, you will swallow a small radioactive iodine capsule.

On your second visit (four hours after taking the capsule), you will have an uptake measurement, pictures of your thyroid gland and an examination of your thyroid gland by the nuclear medicine physician.

You will be in a sitting position for your uptake measurement procedure and lying flat on your back while pictures of your thyroid gland are taken.

The uptake probe used to perform the uptake measurement and the gamma camera used to take pictures of your thyroid gland do not produce any radiation. Each instrument simply detects and/or records the distribution of radioactive material in your thyroid.

Measuring the uptake and taking pictures of your thyroid gland will take approximately one hour.

Finally, on your third visit (24 hours after taking the capsule), you will have a follow-up uptake measurement of your thyroid gland.

This final visit will take approximately five minutes.

After Your Exam

If you stopped your thyroid medication, you must call your physician for instructions before resuming your medication.

Your study will be reviewed by an imaging physician specialist and the results sent to your physician. Your physician will discuss these results with you and explain what they mean in relation to your health.
