A thyroid ultrasound is a diagnostic imaging test used to examine the thyroid gland. It is a non-invasive and painless procedure that uses high-frequency sound waves to create images of the thyroid gland. Normal thyroid ultrasounds are ordered by doctors for various reasons. In this article, we will explore why a doctor would order an ultrasound of the thyroid.
The thyroid gland is located in the neck. It is responsible for producing hormones that regulate metabolism, heart rate, body temperature, and blood pressure. Thyroid hormones are essential for the proper functioning of the body. The thyroid gland may develop various conditions that may cause it to malfunction. The thyroid gland can become enlarged, develop nodules or cysts, or become inflamed. These conditions may cause symptoms that may range from mild to severe. A thyroid ultrasound can expedite the evaluation and identification of the underlying cause of these symptoms by the doctor.

Reasons Why A Doctor Order A Thyroid Ultrasound
To Evaluate The Structure Of The Thyroid Gland
One of the most common reasons is to evaluate the thyroid gland’s size and shape. If the thyroid gland is enlarged, a thyroid ultrasound can help the doctor to determine the cause of the enlargement. An enlarged thyroid gland may be due to various conditions, such as thyroiditis, thyroid nodules, or goiter. Thyroiditis is a condition of the swollen thyroid gland leading to enlargement of the gland. A goiter is an enlarged thyroid gland that is not due to cancer or inflammation. A thyroid ultrasound can help the doctor to differentiate between these conditions and determine the appropriate treatment.
To Gauge the Characteristics of The Gland
Another reason why a doctor may order a thyroid ultrasound is to evaluate the status of the thyroid gland. The thyroid gland may become inflamed and develop Hashimoto’s thyroiditis. Hashimoto’s thyroiditis may cause the thyroid gland to become enlarged and firm to the touch. A thyroid ultrasound can assist the doctor in ascertaining the features of the thyroid gland. It helps determine if it is consistent with Hashimoto’s thyroiditis.
To Evaluate The Presence Of Nodules Or Cysts In The Thyroid Gland
A doctor may also order a thyroid ultrasound to evaluate the presence of nodules or cysts in the thyroid gland. These refer to the unusual growths in the thyroid gland, typically non-cancerous. However, some nodules may be cancerous, and a thyroid ultrasound can help to determine the nature of the nodule. A thyroid nodule that is cancerous may require surgery or other treatments. A thyroid ultrasound can help the doctor to determine if the nodule is causing any symptoms like difficulty swallowing or breathing.
To Monitor The Progression Of Thyroid Cancer
A doctor may also order a thyroid ultrasound to monitor the advancement of thyroid cancer. Thyroid cancer is a rare but serious condition that may necessitate surgical procedures or other treatment modalities. A thyroid ultrasound can help the doctor to determine the size and location of the cancerous cells and monitor their progression over time.
To Evaluate The Thyroid Gland In Pregnant Women
A thyroid ultrasound may also be ordered to evaluate the thyroid gland in pregnant women. Pregnancy may cause changes in the thyroid gland that may require monitoring. A thyroid ultrasound can help the doctor to evaluate the functionality of the gland based on specific metrics. It also determined if any abnormalities may affect the health of the mother or the baby.
A thyroid ultrasound is a non-invasive and painless imaging test. It is used to evaluate the size, shape, texture, and presence of nodules or cysts in the thyroid gland. A doctor may order a thyroid ultrasound to diagnose various conditions, such as thyroiditis, thyroid nodules, or goiter. A thyroid ultrasound may also be ordered to monitor the progression of thyroid cancer or to evaluate the thyroid gland in pregnant women.

Types Of Thyroiditis
Thyroiditis is an inflammation of the thyroid gland that may cause the gland to become enlarged. Thyroiditis is of different types, like subacute and Hashimoto’s thyroiditis. Hashimoto’s thyroiditis is an autoimmune disorder that results in the immune system viewing the thyroid as an invader. Subacute thyroiditis refers to a condition where the thyroid gland becomes swollen and leads to pain and neck tenderness. A thyroid ultrasound can help the doctor to determine if the thyroid gland is enlarged and if the texture of the gland is consistent with thyroiditis. It can help determine the appropriate treatment for the patient.
Thyroid Cancer
Thyroid nodules refer to unusual growth in the thyroid gland, typically non-cancerous. However, some nodules may be cancerous. A thyroid ultrasound can help the doctor to determine the nature of the nodule and if it is causing any symptoms. If the nodule is cancerous, the medical practitioner might suggest an operation or different treatments. If the nodule is not causing any symptoms, the doctor may recommend regular monitoring of the nodule to ensure that it is not growing or changing in nature.
Goiter is an enlarged thyroid gland that is not due to cancer or inflammation. It can help the doctor to determine the cause of the goiter and if it is causing any symptoms. The deficiency of iodine can cause goiter, for which the doctor may suggest iodine supplements. If the goiter is due to an overactive thyroid gland, the doctor may recommend medications to control the thyroid gland.
Thyroid cancer is a rare but serious condition that might need surgery or different treatments. A thyroid ultrasound can help the doctor to determine the size and location of the cancerous cells and monitor their progression over time. These treatments include chemotherapy or radiation therapy. The doctor also recommends other treatments too.
Pregnancy may cause changes in the thyroid gland that may require monitoring. A thyroid ultrasound can help the doctor to determine if the thyroid gland is functioning normally and if there are any abnormalities that may affect the health of the mother or the baby. Pregnancy may also increase the risk of developing thyroid cancer, and a thyroid ultrasound can help highlight any anomalous growths within the region.
Post-Surgery
Besides the reasons mentioned above, a doctor may order a thyroid ultrasound to evaluate the gland after a patient has been treated for a thyroid condition. For example, after a patient has undergone surgery to remove a portion of the thyroid gland, a thyroid ultrasound can help to determine if any cancerous cells were left behind or if the remaining thyroid tissue is functioning properly.
Sometimes, a doctor may order it as a routine screening test. It may be the case if the patient has a family history of thyroid disease or if the patient has other risk factors for developing thyroid conditions, such as exposure to radiation or a history of autoimmune disorders.
It is important to note that a thyroid ultrasound is just one tool doctors use to diagnose and monitor thyroid conditions. Other tests, such as blood tests, may also be necessary to provide a complete picture of the patient’s thyroid health. Sometimes a biopsy may be important to see if it is exhibiting signs of cancer.
If you are experiencing symptoms of a thyroid condition, such as weight changes, fatigue, or changes in heart rate, it is important to speak with your doctor. Your doctor can help you determine if a thyroid ultrasound or other tests are necessary to diagnose and treat your condition.
