Ultrasonography of Thyroid
甲狀腺超聲波
Thyroid ultrasound is a non-invasive examination. Doctors use ultrasound imaging to examine whether there are any abnormal tumors, calcifications, and other conditions within the thyroid gland. It can also check for enlarged lymph nodes in the neck, providing important information for clinical diagnosis.

Thyroid Function Test
甲狀腺功能檢查
The purpose of thyroid function testing is to evaluate the thyroid levels in a patient’s body. Conditions such as hyperthyroidism and hypothyroidism can be diagnosed through a simple blood test. The testing can also help doctors differentiate thyroid function problems caused by different factors.
Typically, thyroid function testing includes measuring the levels of thyroid hormone T4 and thyroid-stimulating hormone (TSH).

Ultrasound-Guided Fine Needle Aspiration
超聲波導引幼針穿刺
If a suspicious thyroid tumor is detected during an ultrasound examination, the doctor may arrange for an ultrasound-guided fine-needle aspiration biopsy. This procedure involves extracting a small amount of cells from the suspicious thyroid tumor for pathological analysis. It helps determine whether the tumor is benign or malignant, as well as its nature or characteristics.

About Thyroid Cysts
When nodules within the thyroid gland grow too rapidly, it can lead to insufficient blood supply and subsequent cellular shrinkage in the affected area, resulting in the formation of a thyroid cyst. Most cysts in the thyroid gland are benign in nature.
The thyroid gland is filled with tiny blood vessels. In the case where the delicate blood vessels on the surface of a cyst bleed, blood can flow into the cyst, causing it to suddenly enlarge and result in pain. This condition is known as a haemorrhagic cyst. Patients may experience sudden pain and swelling in the area of the thyroid. Most hemorrhagic cysts tend to noticeably decrease in size within three to four weeks.
After a physical examination of the neck, doctors generally recommend patients to undergo thyroid ultrasound to differentiate between thyroid cysts and other conditions such as thyroid nodules or cancer. Additionally, doctors can perform ultrasound-guided fine needle aspiration (FNA) on thyroid cysts to extract cells from within the cyst for pathological analysis, which helps determine the nature of the thyroid cells.
Benign and small thyroid cysts can be observed and monitored. Thyroid ultrasound every six months to a year can be performed to check for any abnormal changes in the thyroid cyst. If there are significant size or imaging changes detected during the ultrasound examination, the doctor may arrange for ultrasound-guided fine needle aspiration (FNA) to extract cells for further analysis.
If the condition of the thyroid cyst persists, the doctor may recommend a procedure called cyst aspiration. This involves using a syringe to withdraw the fluid from the cyst under ultrasound guidance, followed by the injection of 100% ethanol into the cyst. This method has a success rate of over 90% in reducing the cyst volume by 70-90%.
If the cyst does not reduce to an ideal size or recurs, the patient may consider repeating the ethanol injection or undergo thyroidectomy, which is the surgical removal of the thyroid gland.
