Thyroid ultrasound can assist in the diagnosis of hyperthyroidism, but cannot confirm the diagnosis. Hyperthyroidism, known as hyperthyroidism, belongs to a group of clinical syndromes, and the diagnosis of hyperthyroidism can be established if the following three items are present at the same time: hypermetabolic symptoms and signs, enlarged thyroid gland and increased levels of serum thyroid hormone, and decreased thyroid stimulating hormone. Color ultrasound is mainly to check the morphology of the thyroid gland, check whether the blood flow signal is normal or not, and can only clarify the presence or absence of goiter. Clinical often after the thyroid function test, when there is a high degree of suspicion of hyperthyroidism, further color ultrasound will be performed to help confirm the diagnosis. Hyperthyroidism needs to be treated after diagnosis, and can be treated with medication, iodine-131 therapy or surgery under the guidance of a doctor, and if there is any discomfort, consult a doctor in time.
