Thyroid Uptake Scan

Nuclear medicine

What is a Thyroid Uptake Scan?

A Thyroid Uptake Scan is a nuclear medicine scan performed to evaluate the size, location, and overall functional level of the thyroid gland. The study is acquired using a small amount of radioactive iodine (123I).

This scan can determine if the patient has thyroid cancer: persistent or recurrent disease, hyperthyroidism and thyroid nodule or goiter assessment.

Preparing For Your Thyroid Uptake Scan

  • No food or drink (4) four hours before your scan.
  • You may wear your own clothing, such as jogging, leggings, or sweat pants, as long as there are no metal fasteners, zippers, buttons, etc. Hospital gowns are available.
  • Jewelry and other accessories should be left at home, if possible, or removed prior to the scan.

Walk-in Patients: Please be sure to bring the signed order from your physician requesting the examination and your insurance card.

What You Can Expect During Your Thyroid Uptake Scan

The Nuclear Medicine equipment used for your scan is performed in an open environment which alleviates discomfort or claustrophobia concerns, as the patient is not fully enclosed.

Your technician will provide a very safe radioactive material (tracer) in the form of a pill to swallow. Once you have taken the pill, you are not required to remain at the facility while waiting for tracer to be absorb into your system. Absorption takes about three (3) hours wait time.

Once you return for the scan, the gamma camera will move around your head and chest area without touching the body to take pictures of the tracer as it moves through your body. This process time varies with each study, during which you will need to remain still.

The scan will take approximately 30–60 minutes.

After Your Thyroid Uptake Scan

In most cases, you can go about your day after your scan. The small amount of radioactive tracer will lose its reactivity or pass through your urine and stool over the next day or two. Drink plenty of water to help flush it out of your system.

How Soon Will Scan Results Be Available?

Your images are reviewed, and results interpreted by one of our qualified doctors who specializes in reading images (radiologist). The Radiologist will prepare a report, which is electronically sent to your doctor as soon as available, usually within 24-48 hours.
