In addition to ultrasound, thyroid nodules also require physical examination, other imaging tests, laboratory tests, and pathologic tests. 1. Physical examination: the physician pushes the trachea to the opposite side with the index, middle and ring fingers of one hand behind the patient’s back, and pushes the thyroid forward with the thumb of the other hand from the opposite side of the sternocleidomastoid muscle, so as to observe whether there is any increase in the size of the thyroid gland. 2. Imaging tests: X-ray of the neck, CT of the neck, and nuclear scanning can be used to see if there are thyroid nodules. 3. Laboratory tests: Test thyroid hormone levels to determine the presence of hyperthyroidism or hypothyroidism, according to the level of thyroid peroxidase antibodies and thyroglobulin antibodies to make a preliminary diagnosis of the presence of Hashimoto’s thyroiditis. 4. Pathological examination: For thyroid nodules of unknown nature or suspected malignancy, a thyroid puncture biopsy can be performed to determine the degree of benignity or malignancy of the nodule. It is recommended that patients suspected of having thyroid nodules should go to regular hospitals in time to improve the relevant examinations and standardize the treatment under the guidance of doctors.
