A thyroid ultrasound exam is used in the diagnosis and treatment of problems with the area of the neck that includes the thyroid gland and parathyroid glands, which produce hormones to control metabolism and the amount of calcium in your blood and bones. The test is commonly performed to investigate thyroid nodules and to determine whether or not the nodules are cancerous or benign.
For your exam, please wear a shirt that allows clear access to your neck or we may have you change into a gown. A gel is applied to your skin to ensure that the transducer (the probe that emits the high-frequency sound waves) has good contact for sound transmission. The technologist firmly presses the transducer to your skin and moves it over your neck area to get images of structures inside the neck.
You should experience no pain or discomfort. The exam takes approximately 30 minutes.
A radiologist will review your exam and a report of your exam will be sent to your doctor, who will discuss the results with you.
