What is it?

The thyroid is a butterfly-shaped gland at the front of the neck. Ultrasound measures its volume, examines its appearance and looks for nodules; it also examines the lymph nodes of the neck. Most thyroid nodules are benign. The doctor describes each nodule (size, outline, content) and may give it a classification score, such as the EU-TIRADS score, which helps your doctor decide between simple monitoring and further tests. If a nodule needs to be analysed, an ultrasound-guided fine-needle aspiration may be offered: it is described on a separate page (ultrasound-guided procedures).

When is it indicated?

Thyroid nodule

It describes the features of the nodule and points towards monitoring or aspiration.

Goitre

It measures the volume of the gland and follows its progress.

Hyperthyroidism, hypothyroidism, thyroiditis

It completes the blood tests by showing the appearance of the gland.

Lymph node or lump in the neck

It clarifies the likely nature of a lump and its relation to nearby organs.

You may be asked to swallow or turn your head

The gel is wiped off; you can return to your usual activities straight away

Duration

About 15 to 20 minutes

Results

The images are analysed by the doctor performing the examination, who writes a report. The report is given to you with the relevant images and sent to your doctor, who will explain the results and the next steps. You will be told when to expect it on the day of the examination.
