Thyroid ultrasound is an examination performed to evaluate the thyroid gland in the neck. Thyroid ultrasound is the most useful test used to detect abnormalities, goiter or nodules in the thyroid gland. Thyroid cancer is also detected by this ultrasound examination.
How Is Thyroid Ultrasound Performed?
Thyroid ultrasound is an examination performed by placing a small piece of the ultrasound device called a probe on your neck as seen in the picture, sending a sound wave and seeing the image of these sound waves on the computer screen.
Since sound waves are used for thyroid ultrasound, it can also be done safely in pregnant women. Thyroid ultrasound also plays an important role in the diagnosis of thyroid cancer.
Benign Disease Types of Thyroid Gland
Goiter: There are two types as diffuse goiter and nodulous goiter. The main symptom of this disease occurs with an overgrowth of the thyroid gland. If there is a nodule, it is necessary to see a radiologist once every 6 months to check whether it has transformed into a malignant one.
Thyroiditis: Non-microbial inflammation of the thyroid gland. It is autoimmune, that is, the antibodies produced by the person’s own immune system attack their own cells. It can also occur during pregnancy. Thyroiditis problem may occur due to hereditary reasons. For example, Hashimoto (Hashimoto) Thyroiditis. Thyroiditis caused by Hashimoto’s disease should be followed closely. If nodules occur in thyroiditis due to Hashimoto’s, a change for the worse may occur. Therefore, follow-up is important.
Types of Malignant Diseases of the Thyroid Gland
Thyroid cancer can also be diagnosed with thyroid ultrasound. In this context;
Papillary Thyroid Ca: Although it is defined as thyroid cancer, it is a relatively benign type of cancer. It can be detected by experienced specialist doctors during the ultrasound performed for the examination of the thyroid gland. If it is noticed during thyroid ultrasound, the diagnosis should be confirmed by thyroid biopsy.
Follicular Thyroid Ca: This type of thyroid cancer, which is usually seen in women over the age of fifty, is a much more aggressive cancer type. It is the most malignant type of cancer of the thyroid gland. Cancer that starts here tends to progress to the lymph nodes. If it is detected during the thyroid ultrasound, a thyroid biopsy is absolutely necessary for a definitive diagnosis.
