The thyroid is a gland located in the neck region which makes a hormone called thyroxine that controls how fast the body converts food into energy (metabolism). Ultrasound can help measure the size and shape of the thyroid gland, but it cannot tell how well the thyroid gland is working.
What happens during the exam?
The patient lies on a table with the neck area exposed. The sonographer (technologist who performs the exam) will put a warm water-based gel on the skin surface. The gel helps to transmit the sound waves by excluding air. An instrument called a transducer, which is about the size of a microphone, will be moved over the skin surface by the sonographer.
