Thyroid Ultrasound

We examine the shape of the thyroid and any nodules, and explain how this differs from thyroid function tests.

A test that looks at appearance is different from a hormone test.

Thyroid ultrasound checks the size and structure of the thyroid at the front of the neck, and the features of any nodules. How much thyroid hormone is produced is assessed with a blood test, so a normal ultrasound alone does not determine thyroid function.

You can hear an explanation during your visit, review what you need to know, and then decide.

Please tell us before the exam.

Changes felt in the neck

Please tell us if there is a lump you can feel, a change in voice, a sense of pressure, or difficulty swallowing.

Previous results

Please bring ultrasound, blood test, and fine-needle aspiration results, along with treatment records.

Personal medical history

We review thyroid disease and surgery, medicines you take, family history, and any history of radiation treatment to the neck.

If a nodule is seen, the next step is decided based on its features.

When observation is needed

Based on size, imaging features, previous changes, and other factors, we discuss whether follow-up is needed and at what interval.

When further evaluation is needed

We may consider whether tissue or cell testing, such as fine-needle aspiration, is needed. Not every nodule is cancer, and not every nodule needs to be removed right away.

Having more tests is not always better.

Individual need

We decide whether testing is needed based on symptoms, risk, and previous findings. We do not advise that a thyroid exam is required just because you are having a breast ultrasound.

In-clinic and referral scope

Please have us explain, separately, what can be assessed at the clinic and when additional tests or specialist care are needed.

Frequently Asked Questions

Does ultrasound confirm whether it is cancer?

Imaging can help assess risk, but additional checks such as cytology or tissue testing may be done if needed. Please have the results and the next plan explained together.

Feel free to bring your questions.

Please tell us what is bothering you and your previous examination and treatment history. Together we will confirm the care you need.
