Diagram A thyroid ultrasound uses a probe placed on the front of the neck; it involves no radiation.

Thyroid ultrasound is an important imaging method used to assess the structure and function of the thyroid gland. This examination helps to detect nodules, cysts or other abnormalities in the thyroid gland. Here are the key points about thyroid ultrasound:

1. Quick: Thyroid ultrasound is usually completed within 15–⁠30 minutes.
2. Safe: As no radiation is used, thyroid ultrasound is a safe imaging method. It is also a recommended option for pregnant women.
3. Nodule assessment: Thyroid nodules are frequently detected by ultrasound. The size, shape and internal structure of these nodules provide information about the risk of cancer.
4. Detecting cysts: Ultrasound helps to distinguish fluid-filled cysts from solid lesions. This is an important step in treatment planning.
5. Monitoring thyroid disease: Ultrasound is used to monitor thyroid diseases and conditions such as hyperthyroidism or hypothyroidism. This is important for assessing how effective the course of treatment is.
6. The doctor’s interpretation: Ultrasound results are usually interpreted by the patient’s doctor. This matters for an accurate diagnosis and the right course of treatment.

Thyroid ultrasound is therefore central to assessing the thyroid, and it helps both patients and doctors to understand the condition of the gland.
