Description
Estimated cost for Thyroid Ultrasound at general public hospitals in China is about ¥140-280, and at Grade 3A hospitals about ¥200-350, varying by hospital tier and region.
Main Uses
The primary purposes of a thyroid ultrasound include: evaluating the size and shape of the thyroid gland, detecting the presence and characteristics of thyroid nodules or cysts, assessing blood flow within the thyroid, guiding fine needle aspiration biopsies, and monitoring changes over time in patients with known thyroid conditions. It is particularly useful for diagnosing thyroid cancer, managing thyroid nodules, and following up on treatment effectiveness.
Normal Range
Thyroid ultrasound does not have a specific numerical range like blood tests. Instead, it evaluates the thyroid gland's structure and appearance. A normal result typically indicates: no nodules or cysts, uniform echogenicity, and no signs of inflammation or enlargement. The size of the thyroid gland is also assessed, with a normal adult thyroid measuring approximately 4-6 cm in length, 1-2 cm in width, and 1-2 cm in depth.
Low Values - Possible Causes
Since thyroid ultrasound measures structural and physical characteristics rather than biochemical values, 'low' results are not applicable. However, findings such as a smaller than normal thyroid (hypothyroidism) can be due to: autoimmune diseases (e.g., Hashimoto's thyroiditis), iodine deficiency, congenital hypothyroidism, or previous thyroid surgery.
High Values - Possible Causes
Similarly, 'high' values do not apply, but an enlarged thyroid (goiter) or presence of nodules may indicate: iodine deficiency, Graves' disease, thyroiditis, benign or malignant tumors, or multinodular goiter.
