Can you tell me what the thyroid ultrasound sees?

Anatomy of thyroid. The ultrasound is a technique using sound waves to look inside the body. The thyroid ultrasound exam specifically measure the thyroid gland size (to assess for enlargement or shrinkage), the thyroid texture (for autoimmune or inflammatory diseases that cause heterogeneity), presence of lumps (nodules that may be benign or cancerous), and the amount of blood flow (increase in certain conditions).
