How Long Is a Thyroid Ultrasound?

A thyroid ultrasound is a non-invasive imaging test used to examine the thyroid gland. It is a painless procedure that uses sound waves to produce detailed images of the thyroid, helping physicians diagnose and monitor conditions such as thyroid nodules, goiters, and thyroid cancer. Many individuals wonder about the duration of a thyroid ultrasound, so let’s dive into the details.

The length of a thyroid ultrasound can vary depending on various factors such as the purpose of the examination and the complexity of the case. On average, a thyroid ultrasound takes around 15 to 30 minutes to complete. However, this time frame can be shorter or longer based on individual circumstances.

During a thyroid ultrasound, an ultrasound technician or radiologist will apply a gel to your neck area to ensure proper contact between the ultrasound transducer and your skin. The technician will then use the transducer to move along your neck, capturing images of your thyroid from different angles. They may also ask you to change positions or hold your breath briefly to obtain better images.

Now, let’s address some frequently asked questions about thyroid ultrasounds:

1. Why do I need a thyroid ultrasound?
