Cost of a Thyroid Ultrasound
A thyroid ultrasound is a painless, radiation-free scan that shows the size, texture and structure of the gland and any nodules. It is one of the most useful and affordable imaging tests for the thyroid.
This page explains what the scan involves and what determines its cost.

What the scan includes
The examination takes roughly 15–30 minutes. A gel is applied to the neck and a small probe is moved over the area. The sonographer captures images of the gland and any nodules, then a radiologist reports the findings.
The fee normally covers the scan and a written report. It does not usually include a specialist consultation to interpret what the report means for you.
What affects the price
Cost varies with the imaging centre, whether a radiologist personally performs the scan, the detail of the report, and whether other neck structures (such as lymph nodes) are also assessed.
Hospital imaging departments and standalone imaging centres can price differently. More detailed, specialist reporting may cost more but gives clearer guidance on whether a nodule needs biopsy.
When it is worth having
Ultrasound is most valuable when there is a palpable lump, a visible goitre, an abnormal thyroid test, or a known nodule that needs monitoring. It is not routinely needed for straightforward hypothyroidism with a normal-feeling gland.
If a nodule is found, the ultrasound report guides whether a biopsy is needed — so a good-quality scan can save unnecessary procedures.
Frequently asked questions
Is a thyroid ultrasound expensive?
It is a relatively low-cost imaging test compared with CT or MRI. The exact price depends on the centre and the detail of the report.
Is the scan painful or harmful?
No — it is painless, non-invasive and uses no radiation. You simply lie still while the probe is moved over your neck.
Do I need a doctor’s referral for an ultrasound?
Requirements vary by centre. Many accept direct bookings, but a referral from a clinician who will interpret the result is often helpful.
