放射性同位素能够自发地由原子核内部放出三种看不见、摸不着的核射线,分别命名为α、β、γ射线,广泛应用于临床。本文仅就放射性同位素在诊断和治疗甲状腺疾病中的应用怍一粗浅介绍。甲状腺吸碘功能检查甲状腺是人体内重要的内分泌腺体之一,它主要的生理功能是以碘为原料合成、储存、分泌甲状腺激素(T_3,T_4),促进、调节机体的生长发育以及新陈代谢过程。正常生理情况下,甲状腺对碘具有一定的摄取数量,速率和摄取规律。在甲状腺功能异常时,甲状 Radioactive isotopes can spontaneously emit three invisible and invisible nuclear radiation from the nucleus, which are named α, β and γ rays respectively and are widely used in clinic. This article only on radioisotopes in the diagnosis and treatment of thyroid disease 怍 a superficial introduction. Thyroid function of iodine absorption test Thyroid gland is one of the important endocrine glands in human body. Its main physiological function is to synthesize, store and secrete thyroid hormones (T_3 and T_4) with iodine as the raw material to promote and regulate the growth and metabolism of the body . Under normal physiological conditions, thyroid iodine has a certain amount of intake, rate and intake patterns. In thyroid dysfunction, thyroid
