Our specialized Denver radiologists use thyroid ultrasound to generate images of the thyroid gland to evaluate its health. A thyroid ultrasound will show any masses or subtle changes in the thyroid gland that could be associated with benign (non-cancerous) versus malignant (cancerous) nodules. Most nodules of the thyroid are benign.
The thyroid is part of the endocrine system that affects the body's metabolism and growth. It is a small butterfly-shaped gland that lies in front of the trachea and is responsible for producing hormones to make many cells in your body function correctly. Its proper or improper function can affect our energy level, ability to sleep, muscle and digestive process, brain function, mood, ability to maintain a healthy heart rate, and optimal bone density.
Normal thyroid gland function is significant for women's health as its function or dysfunction may cause problems with fertility and pregnancy. A thyroid ultrasound uses sound waves to produce images and investigate potential issues. Your doctor may order a thyroid ultrasound if they notice physiologic changes, such as thyroid enlargement, redness of the neck, or growth palpated on examination. If you experience swelling or difficulty swallowing, that may also indicate the need for a thyroid ultrasound.
Changes in the thyroid that may need to be examined with ultrasound include:
Nodules
Goiter
Enlargement
Swelling or inflammation
Neck redness
A thyroid goiter is when the thyroid enlarges all over. A goiter may occur because of iodine deficiency related to inadequate or poor nutrition. This condition is uncommon in developed countries but still occurs in the non-coastal United States because the soil lacks iodine, resulting in the food grown there to lack iodine. Iodine is critical for the thyroid gland to function properly. When the gland enlarges because of multiple nodules, this condition is called Multinodular Goiter. We can use medical diagnostic imaging to determine if the reason for the thyroid enlargement is because of many nodules or diffuse inflammation.
Autoimmune conditions such as Graves disease or Hashimoto's Thyroiditis can cause the thyroid gland to enlarge. As injury atrophies the gland over time, it becomes smaller. If the gland is actively inflamed, followed by an abrupt change in function, swelling, or neck redness, blood tests may show a sudden overproduction of hormones or antibodies to the gland or its receptors. This condition is known as toxic thyroiditis, which can be dangerous if essential functions such as heart rate or temperature are involved.
Sometimes a solitary thyroid nodule develops and affects only one area of the thyroid. This process usually requires an ultrasound of the thyroid gland.
Ultrasound of the thyroid uses a small hand-held transducer or wand that emits sound waves produced by special crystals sent to and from the transducer to the thyroid gland. Sound waves reflected back to the crystals in the transducer are displayed as X-ray images of the gland for a specialized radiologist to interpret. This process is also sometimes referred to as a sonogram of the thyroid.
Unlike almost all other radiology centers, a radiologist at The Women's Imaging Center directly oversees the procedure and personally examines you if there is a thyroid abnormality or concern. A thyroid ultrasound will include:
