Thyroid Gland Ultrasound Scan: Unveiling Insights for Health Excellence


When it comes to health, understanding the body and how it functions is essential to maintaining good health. One crucial aspect of this is the thyroid gland which is a small but vital organ in the neck which plays a significant role in regulating the body’s metabolism. If any thyroid-related issues are suspected then a thyroid ultrasound scan can provide valuable insights. In this blog post we’ll discuss what thyroid ultrasound scans are, why they are performed, what to expect during the procedure and what the results may mean in relation to thyroid health.

What is a thyroid gland ultrasound scan?

An ultrasound is a painless procedure that uses sound waves to generate images of the inside of your body. It is a non-invasive imaging test which utilises high-frequency sound waves to create detailed images of the thyroid gland. These images are then used to evaluate the size, shape, texture, and overall health of the thyroid.

Why are thyroid gland ultrasound scan performed?

A thyroid ultrasound may be ordered if a thyroid function test is abnormal or if a growth is felt on the neck during examination. An ultrasound can also check an underactive or overactive thyroid gland. Ultrasounds can provide high-resolution images of the organs which can help clinicians better understand one’s general health. Clinicians may also order an ultrasound if they notice any abnormal swelling, pain, or infections so that they can uncover any underlying conditions that might be causing these symptoms.

Thyroid ultrasound scans may be used to evaluate any of the following aspects of the thyroid:

  • Evaluation of thyroid nodules: One of the primary reasons for a thyroid ultrasound is to assess thyroid nodules. Thyroid nodules are small lumps or growths that can form within the thyroid gland. While most nodules are benign (non-cancerous), some may be cancerous or have potential to be cancerous. A thyroid can help determine the nature of these nodules.
  • Monitoring thyroid conditions: If someone has a known thyroid condition then their healthcare provider may recommend frequent ultrasounds to monitor the glands size and evaluate any changes in its appearance.
  • Assessment of thyroid function: In some cases, thyroid ultrasound scans are used in conjunction with other thyroid function tests to assess overall thyroid health.
  • Guidance for procedures: Thyroid ultrasound can also be used as a guide for certain procedures, such as biopsies. These are performed in order to attain a sample of cells from within a thyroid nodule to be analysed, helping to determine whether it is benign or malignant.


What to expect during an ultrasound scan

Before the procedure, necklaces and other accessories that may block the throat are removed for ease of access. Patients will lie on their back for the examination, with a pillow of pad placed under to expose the neck. In some cases, patients may be required to some upright for parts of the scan.

A cold gel is applied to the neck, known as transducer jelly, this gel helps the probe make better contact with the skin and attain better images. The technician or doctor conducting the scan will then use an ultrasound probe which will be pressed and moved across the skin of the neck capturing images of the thyroid in real time. 

The images captured during the scan are displayed on the accompanying monitor which allows the clinician conducting the scan to later evaluate the thyroid gland and any potential abnormalities.

The entire process is painless and easy, typically taking 15-30 minutes in total.


Understanding thyroid gland ultrasound scan results

After the scan is completed, the images are then analysed by a sonographer or doctor. A thyroid ultrasound can give the healthcare provider a lot of valuable information, including:

  • Nodule characteristics: The ultrasound scan can help determine if any nodules are present, and evaluate their size, location, and whether they are solid or fluid-filled (cystic) and whether they have distinct boundaries.
  • Thyroid size: The scan is also able to assess the overall size and shape of the thyroid gland.
  • Blood flow: In some cases, a doppler ultrasound is carried out to assess blood flow within the thyroid gland, which can be helpful in diagnosing certain thyroid conditions.
  • Guidance for further testing: Depending on the outcome of the ultrasound scan and the findings, healthcare providers may recommend additional tests or procedures, such as a biopsy, to further evaluate any suspicious nodules.

The results are analysed and patients are often consulted after regarding possible follow-up tests or conditions that may be indicated by the ultrasound scan.  


Thyroid ultrasound scans are a valuable diagnostic tool in the s=assessment of thyroid health. Whether there are symptoms of thyroid dysfunction or if the scans are being performed to monitor a known thyroid condition, a thyroid ultrasound can provide crucial information for diagnosis and treatment planning. When recommended for a thyroid ultrasound, don’t hesitate to ask questions and voice any concerns. Being informed and proactive about one’s health is an important for maintaining one’s well-being.
