Description
A thyroid ultrasound evaluates thyroid structure and nodules to diagnose conditions like goiter or cancer; patients in China may need it for symptoms or follow-up, with costs typically 200–500 RMB and ChinaMedicalHub assisting with hospital booking and interpreter support.
Main Uses
The primary purposes and applicable scenarios for a thyroid ultrasound include: 1. Evaluating thyroid gland size and structure, 2. Detecting and characterizing thyroid nodules, 3. Assessing blood flow to the thyroid (vascularity), 4. Monitoring changes in thyroid nodules over time, 5. Guiding fine-needle aspiration biopsy, 6. Diagnosing thyroiditis and other inflammatory conditions, 7. Assessing the impact of treatments such as surgery or radiation therapy
Normal Range
The normal range for a thyroid ultrasound typically includes: Thyroid gland size (volume) within 10-20 mL, no nodules or cysts, homogeneous echotexture, and normal vascularity. The specific values can vary slightly based on the individual's age, sex, and body size.
Low Values - Possible Causes
Low values in a thyroid ultrasound, such as reduced gland size, may be caused by: 1. Iodine deficiency, 2. Autoimmune thyroiditis (Hashimoto's disease), 3. Post-surgical or post-radiation treatment, 4. Congenital hypothyroidism, 5. Severe malnutrition
High Values - Possible Causes
High values in a thyroid ultrasound, such as enlarged gland size or presence of nodules, may be caused by: 1. Goiter (iodine deficiency or autoimmune conditions like Graves' disease), 2. Thyroid nodules (benign or malignant), 3. Multinodular goiter, 4. Inflammation (thyroiditis), 5. Hyperthyroidism
