甲状腺的大小、年龄和性别间的关系是一个有争议的问题,有人认为女性正常的甲状腺大于男性正常的甲状腺。甲状腺体积是否随着年龄变化亦未确定。而且在甲状腺体积和体重之间的关系也无明确的报告。本研究中用精确的超声波扫描法测定了正常人甲状腺体积。在我们的实验室中,此法曾用于估价经 T_3、T_4治疗后甲状腺病人的 The relationship between thyroid size, age and sex is a matter of debate, and some people think that the normal female thyroid gland is larger than the normal male thyroid gland. Whether thyroid volume changes with age has not been determined. There is also no clear report on the relationship between thyroid volume and body weight.
