If your GP or specialist has sent you for a thyroid ultrasound, the appointment is simpler than it might sound. It is a gel-based scan of your neck, performed by a sonographer, with no needles and no radiation. Most people need very little preparation beyond bringing their referral and wearing clothing that leaves the neck clear. At our Menai NSW clinic, we capture the images and send a report to the doctor who referred you, who then talks you through what it means. This guide walks you through each step so nothing on the day comes as a surprise.
Key Takeaways
- A referred thyroid or neck ultrasound needs a valid GP or specialist referral. We cannot book a diagnostic scan without one.
- Preparation is usually minimal: bring your referral, wear a loose top and leave necklaces at home. Check with us when you book in case your situation is different.
- During the scan you lie back with your neck gently extended while the sonographer moves a handheld probe over gel on your skin.
- The sonographer captures the images and a report goes to your referring doctor, who explains the findings and the next steps.
Thyroid ultrasound: what the scan looks at
At our Menai NSW clinic, a thyroid ultrasound uses high-frequency sound waves to create live pictures of the thyroid gland, the small butterfly-shaped gland at the front of your neck. The sound waves are harmless and painless, and the probe simply rests on your skin. Because the gland sits close to the surface, ultrasound is a practical way for your doctor to see its size, shape and internal structure.
The scan can also include the surrounding neck tissue, depending on what your referral asks for. We list thyroid and neck ultrasound as one of our referred diagnostic services, and the referral tells the sonographer which areas your doctor wants imaged. Ultrasound is the only imaging type we perform, so if your referral names something different, it is worth checking with your referring doctor.
You may also see the term “thyroid scan” used by patients and in search results. In everyday conversation it often just means an ultrasound of the thyroid, but it can sometimes mean other tests. If you are unsure which test your doctor has requested, ask them before you book.
Why a doctor might request a neck or thyroid nodule ultrasound
We do not diagnose conditions, and we cannot tell you why your own doctor ordered your scan. In general terms, though, doctors request a neck ultrasound for a range of reasons. You might have noticed a lump or swelling at the front of your neck. Your doctor might have felt something during an examination, or a blood test result might have prompted a closer look. Sometimes a scan is requested to follow up on something found earlier, or to keep an eye on an area over time.
A thyroid nodule ultrasound is one common example. A nodule is simply a lump within the thyroid, and ultrasound can show its position, its size and how it appears on the image. What those features mean for you is a medical judgement that belongs to your referring doctor, who knows your history, your symptoms and your other test results.
If you have been given a referral and you are feeling anxious, that is a very understandable reaction. A referral is a request for more information. It is not a result in itself.
Getting your referral and booking the appointment
Every diagnostic ultrasound we perform requires a valid referral from a GP or specialist. Your ultrasound referral should name the area to be scanned, and it helps if it includes a short note on why the scan is needed. Bring the original or a clear digital copy to your appointment.
To book, contact us using the details at the end of this article. Our Menai clinic is at 10 Anzac Rd, and we currently run evening appointments from Monday to Thursday (6:30pm to 8:30pm) and Saturday mornings (8:00am to 12:00pm). Those times suit people who work during the day. Since schedules can change, confirm the current availability when you call.
On cost, we are not a bulk-billing provider. Referred diagnostic scans may attract a Medicare rebate where current eligibility and item requirements apply, but we cannot guarantee a rebate or tell you your out-of-pocket amount in an article. Ask us about current fees when you book, so you know what to expect before you arrive.
How to prepare for your thyroid or neck scan
Preparation for this type of scan is generally straightforward, and it is quite different from some abdominal ultrasounds that ask you to fast or arrive with a full bladder. Even so, always confirm with us when you book, particularly if your referral includes more than one area. Here is a practical checklist:
- Bring your referral. We cannot perform a diagnostic scan without it.
- Bring previous imaging reports. If you have had earlier neck or thyroid scans, having them to hand can help the sonographer understand what your doctor is following up.
- Wear easy clothing. A top with a loose or open neckline works best, as the sonographer needs clear access to your neck and the base of it.
- Leave jewellery at home. Necklaces and scarves can get in the way and may be uncomfortable once gel is applied.
- Tie up long hair. This keeps it clear of the gel and the probe.
- Bring your questions. Write down anything you want to raise with your referring doctor afterwards, because that is where the discussion about results happens.
Arrive a few minutes early so that there is time for check-in, and let us know if you have any difficulty lying flat or tilting your head back. We can usually adjust positioning to keep you comfortable, so just say so.

What happens during the scan itself
Understanding the sequence often takes much of the worry out of the day. Here is what a thyroid ultrasound appointment typically looks like at our clinic.
First, the sonographer will check your details and your referral and explain what they are about to do. You will then lie on your back on the examination bed, usually with a small pillow or cushion under your shoulders so your neck can extend gently. Next, the sonographer applies a water-based gel to the front of your neck. The gel can feel cool at first, and it wipes off easily afterwards.
The sonographer then glides a small handheld probe over the gel, pressing lightly. You will not feel the sound waves. Most people describe the pressure as mild. During the scan you may be asked to turn your head slightly to one side, hold still for a moment, or swallow so that the gland can be viewed as it moves. The sonographer takes images and measurements of the areas listed on your referral, and may look at the neck from several angles.
The scan takes the pictures; your referring doctor explains what they mean for you.
Our sonographers have more than 15 years of medical-imaging experience, and they will keep you informed about what they are doing. They are not able to interpret your images or discuss what they might mean while you are in the room. This can feel a little frustrating if you are hoping for answers, but it exists for good reason: a complete picture requires the whole set of images, your history and your doctor’s clinical judgement.
We do not promise a set appointment length, because it depends on what has been requested and how much needs to be imaged. Ask us when you book if you need to plan around work or family commitments.
After the scan: how results reach your referrer
Once your images are captured, they are reviewed and a diagnostic report is prepared for the doctor who referred you. That report goes to your referring GP or specialist, and they are the person who talks you through the findings. We cannot interpret your scan or tell you what your result means, and we do not guarantee when a report will be ready.
The practical step for you is to book a follow-up with your referring doctor, so you can discuss the outcome and anything that needs to happen next. If you are waiting and feel unsure how long to expect, a call to your doctor’s rooms is often the quickest way to find out when they receive reports.
If your symptoms change, get worse or feel urgent while you are waiting, do not wait for a scan appointment or report. Contact your GP promptly, or go to an emergency department for anything severe or sudden, such as difficulty breathing or swallowing. A booking form is not the right pathway for urgent symptoms.
Referred scans and keepsake scans are different services
UBM Scans runs two separate arms. Referred diagnostic ultrasound, including thyroid and neck, is medical imaging that requires a GP or specialist referral. Our keepsake pregnancy scans are a different, non-diagnostic service that needs no referral. If you are curious about the difference between those experiences, our guide to 2D, 3D and 4D ultrasound explained covers how ultrasound technology works in a keepsake setting.
If someone in your family is expecting and wondering about early pregnancy options, our comprehensive guide to reassurance scans explains that separate service. Keep in mind that keepsake scans are not a substitute for care from a doctor or midwife, and they are not related to your own thyroid appointment.
Frequently Asked Questions
Do I need a referral for a thyroid ultrasound?
Yes. Every diagnostic ultrasound at UBM Scans requires a valid referral from a GP or specialist. Without one, we are unable to book the scan.
Does a thyroid ultrasound hurt?
Most people find it comfortable. The probe applies light pressure and the gel may feel cool. If you feel uncomfortable at any point, tell the sonographer and they can adjust their technique or your position.
Do I need to fast or drink water beforehand?
Thyroid and neck scans do not usually come with the fasting or full-bladder instructions that apply to some other ultrasounds. Still, confirm with us when you book, especially if your referral lists more than one area.
Will the sonographer tell me my results?
No. Our sonographers capture the images, but interpreting them belongs to the clinical process. A report goes to your referring doctor, who will explain the findings and discuss what comes next.
Will Medicare cover my scan?
Referred diagnostic scans may attract a Medicare rebate where current eligibility and item requirements apply, but we cannot guarantee a rebate or an amount. We are not a bulk-billing provider, so please ask us about current fees when you book.
Going into your thyroid appointment feeling prepared
A referred neck scan is a short, non-invasive appointment, and knowing the steps in advance makes it easier. Bring your referral, wear something that leaves your neck clear, and expect a gentle, gel-based scan while you rest on the bed.
What happens next is handled by your doctor. The sonographer’s role is to capture careful images, and your referring GP or specialist reads the report and explains what it means for you and your care.
If anything about the appointment is unclear, a quick call before you arrive is the simplest way to settle it. We would rather answer your questions early than have you walk in unsure.
