Thyroid Ultrasound – Indications, Preparation and Course of Thyroid Ultrasound
Thyroid ultrasound (USV thyroid) is a non-invasive diagnostic method that uses sound waves to visualize the thyroid gland. This examination allows doctors to assess the size, shape, structure and possible abnormalities of the thyroid gland, such as nodules, cysts and tumors.
Indications for thyroid ultrasound
- Changes in thyroid function
Irregularities in thyroid hormone levels (TSH, T3, T4). Symptoms of hyperfunction (hyperthyroidism) or hypofunction (hypothyroidism) of the thyroid gland.
- Palpable masses or nodules
The presence of palpable masses or nodules in the neck.
- Abnormalities found on other tests Irregularities found on blood tests or thyroid scans.
- Family history of thyroid disease
A genetic predisposition to thyroid disease.
- Compression symptoms
Difficulty swallowing, breathing, or a feeling of pressure in the neck.
Preparing for a thyroid ultrasound
There is no need to fast or take any special precautions. Wear clothing that allows easy access to the neck (e.g., a V-neck top or shirt).
Thyroid ultrasound
The patient lies on his back, with his neck slightly tilted back to make it easier to access the thyroid gland. A special gel is applied to the neck to help the sound waves travel. A doctor or technician moves a probe through your neck, directing sound waves toward your thyroid gland. The probe sends out sound waves that bounce off your thyroid tissue and create a real-time image on a screen. The exam usually takes between 15 and 30 minutes.
After your thyroid ultrasound
A radiologist or doctor will analyze the images and write a report for you. Based on the results of the ultrasound, your doctor may recommend additional tests, such as a biopsy, blood tests, or a consultation with an endocrinologist.
A thyroid ultrasound is a safe, noninvasive, and painless procedure that provides important information about your thyroid. This test is essential in diagnosing and monitoring thyroid disease. If you have thyroid-related symptoms or abnormalities found on other tests, a thyroid ultrasound can help with further diagnosis and treatment.
