Thyroid disorders are now increasingly recognized as thyroid disorders can lead to hyperthyroidism, hypothyroidism, thyroid nodules, thyroid tumors, etc. The common examination items include the following: first is blood test, such as perfecting thyroid hormone, which can check six items of thyroid function, eight items of thyroid function, three items of thyroid function and five items of thyroid function, to determine whether the patient has hypothyroidism or hyperthyroidism. Next is the iodine 131 test as well as the technetium element test, which can determine the absorption of the thyroid gland, whether it is a cold or hot nodule. In addition, a thyroid ultrasound can be performed, which can determine the size of the patient’s thyroid gland, whether it is cystic or solid, and the condition of the surrounding lymph nodes. An MRI can also be done to further clarify the relationship between the thyroid gland and the surrounding esophagus and trachea and to clearly determine the size.
