What’s a Thyroid Ultrasound? Thyroid Ultrasound Explained: When You Need One and What It Shows
A thyroid ultrasound is a safe, painless test that uses sound waves to take pictures of your thyroid gland. The thyroid is a small butterfly-shaped gland in your neck that controls how your body uses energy. This scan helps doctors check for problems like thyroid nodules, cysts, or swelling without using radiation. It’s one of the most common and effective ways to look closely at the thyroid and surrounding neck structures.
When You Might Need a Thyroid Ultrasound
Your doctor may recommend a thyroid ultrasound if they feel a lump in your neck or notice changes in your thyroid blood tests. Common reasons for this scan include:
Checking thyroid nodules or lumps found during a physical exam Monitoring cysts or growths over time Evaluating swelling in the neck or thyroid gland Guiding a needle biopsy to test suspicious areas Following up after thyroid surgery or treatment
What a Thyroid Ultrasound Can Show
A thyroid ultrasound can provide detailed images to help detect:
Thyroid nodules (solid or fluid-filled lumps) Cysts in the thyroid gland Enlargement of the thyroid (goiter) Signs of thyroiditis (inflammation) Abnormal blood flow in the thyroid Suspicious features that may need a biopsy
The Thyroid Ultrasound Process
Getting a thyroid ultrasound is quick and simple. Here’s what you can expect:
You will lie on your back with your neck slightly tilted back A gel will be applied to your neck to help the ultrasound probe glide smoothly The technologist will move the probe over your thyroid area to capture images The scan usually takes 15–30 minutes and you can return to normal activities right after
How to Prepare for a Thyroid Ultrasound
Wear a loose shirt or top with an open neckline for easy access to your neck Remove necklaces or scarves before the scan No fasting or special preparation is needed
Understanding Your Results
