Welcome to Radiology Info dot org!
Hello, I’m Dr. Geoffrey Rubin, a radiologist at Duke University in Durham, North Carolina. I’d like to talk with you about ultrasound imaging of the thyroid also known as thyroid ultrasound or sonography.
Thyroid sonography uses sound waves to produce pictures of your thyroid gland which is in the front of your neck and controls your body’s metabolism. This exam is commonly used to evaluate lumps or nodules found during a routine physical or other imaging exam.
A thyroid ultrasound requires no special preparation. Wear loose, comfortable clothing and leave any jewelry at home. You may be asked to change into a gown.
During the procedure, you will lie on your back. The sonographer, who is a specialist in using ultrasound, will place warmed gel on your skin and then pass a transducer over the surface of your neck to see inside.
Thyroid ultrasound does not involve needles or injections. While it may be temporarily uncomfortable, an ultrasound exam is almost never painful.
Ultrasound is also extremely safe, and does not use radiation. It provides a clear picture of soft tissues that do not show up well on x-ray images. And, ultrasound has no harmful effects.

Thank you for your time!
