【摘要】 文章用核医学方法检查甲状腺机制亢进症40例、亚急性甲状腺炎12例及无痛性甲状腺炎21例。甲亢组FT₃/FT₄值大于0.24（pmol/pmol）,而全部亚甲炎和无痛性甲炎的FT₃/FT₄值均小0.24。认为此比值像甲状腺吸¹³¹I率一样,在甲亢与无痛性甲炎的鉴别诊断方面是有价值的。更多还原

【Abstract】 Thyroid function was tested in patients with hyperthyroidism （40 cases）, subacute thyroiditis （12） and painless thyroiditis （21）. The serum free triiodothyronine/free thyroxine ratio value （FT₃/FT₄）was>0.24 pmol/pmol in hyperthyroidism but<0.24 in 11/12 patients with subacute thyroiditis and 20/21 patients with painless thyroiditis. Therefore, like RAIU of thyroid, the serum FT₃/FT₄ ratio value is useful for differentiating painless thyroiditis from the hyperthyroidism of Graves’ disease.更多还原
