What Is A Thyroid Ultrasound?
A thyroid ultrasound is a non-invasive imaging exam that uses sound waves to create pictures of the thyroid gland and nearby structures in the neck. It does not use radiation.
The thyroid is a small gland that helps regulate important body functions through hormone production. Ultrasound may help evaluate the size, shape, and appearance of the thyroid, including nodules or other findings.
Why Consider A Thyroid Ultrasound?
A thyroid ultrasound may be worth considering if you have:
- A thyroid nodule
- A lump or fullness in the neck
- Family history of thyroid concerns
- Abnormal thyroid findings discussed with a provider
- Prior thyroid findings that need monitoring
- A desire for more information about thyroid structure
In reviewed Visionary Thyroid Ultrasound entries, findings were noted in approximately 53% of reviewed results. These findings are imaging observations, not confirmed diagnoses, and may require follow-up with a qualified healthcare provider.
How Is A Thyroid Ultrasound Performed?
During a thyroid ultrasound, you lie on an exam table with your neck positioned so the thyroid area can be imaged clearly. Gel is applied to the skin, and a handheld transducer is moved over the front of the neck.
The exam is non-invasive, does not require sedation, and usually requires little to no preparation.
What To Expect After A Thyroid Ultrasound
After the ultrasound, you can return to normal activities. There is no downtime.
Your results are reviewed and organized into a report. If nodules or other findings are noted, you can share the report with your healthcare provider to discuss follow-up, monitoring, lab work, or additional evaluation.
