Thyroid Ultrasound

What is a Thyroid Ultrasound?

Ultrasound uses sound waves to create images of tissue inside the body; it does not use X-ray or radiation. Thyroid Ultrasound may be ordered when fullness or a lump in your neck is felt by your provider or as follow-up to certain blood test results. The exam determines the size and shape of your thyroid gland. Ultrasound can also detect abnormalities of the thyroid gland, such as cysts or tumors.

Before the Exam

Providing safe, quality patient care is our highest priority. For the best experience please properly prepare for your appointment:

• No special preparation is required. You may eat and drink as normal.

During the Exam

• A registered sonographer will perform the exam.
• You will lie on your back on an exam table. To open neck space needed for the exam, a pillow will not be used under your head. Depending on the size of your thyroid gland, you may be asked to place the pillow under your shoulder to extend the neck.
• Warm gel will be placed on the neck. The gel is needed for sound waves to travel and create images.
• A small device, called a transducer, will be moved over your skin to create images on the ultrasound monitor. Several images and measurements will be recorded.
• It takes approximately 30 minutes to complete the exam.

After the Exam

• You may resume your normal diet and activity immediately following the exam.
• A radiologist reviews the images and prepares a report for your provider. The results of your exam will be given to you by the ordering clinic.
• Follow-up care is a key part of your health. Be sure to make and go to all appointments and call your primary care provider if you have questions.
