放射性碘治疗是怎么做的 贾克宝 首都医科大学宣武医院 放射性的碘治疗就是放射性碘，咱们用的最常见的就是碘131，这种碘131是有放射性，让病人口服进去或者静脉打进去以后，这种放射性的碘是聚集在甲状腺的，当你甲亢的时候这种放射性碘聚集在甲状腺部位，它是慢慢地发出β射线对甲状腺的滤泡细胞慢慢地给它杀死，杀到一定程度，甲状腺功能就正常了，甚至就大多数人都变成甲状腺功能低下了，但是这个是需要一个很长的时间，它最禁忌症就是怀孕期间叫妊娠妇女和哺乳期的妇女是坚决不允许碘131治疗的，妊娠期如果用碘131治疗对小孩是有影响的，因为它虽然放射线很短，这种β射线，再短它跟小孩要亲密接触，这种是不允许的，这种放射性对小孩应该说对各个系统都可能有损害，因为哺乳期也一样的，因为产妇或者孕妇要跟小孩亲密接触，放射性毕竟是一个放射性的东西，因为小孩还正在发育阶段吗，对所有的系统可能都会有损伤，尽量在妊娠期和哺乳期不能用碘131治疗。 How to do radioiodine therapy Radioactive iodine therapy is radioactive iodine, The most common one we use is iodine 131, This iodine-131 is radioactive, After the patient is given oral or intravenous injection, This radioactive iodine is concentrated in the thyroid gland, When you have hyperthyroidism, this radioactive iodine accumulates in the thyroid, It slowly sends out beta rays to the follicular cells of the thyroid gland and slowly kills it, To a certain extent, The thyroid function is normal, Even most people have hypothyroidism, But it will take a long time, The most contraindication is that pregnant women and lactating women are not allowed to use iodine-131, If iodine-131 is used in pregnancy, it will affect children, Because although the radiation is very short, This beta ray, If it's shorter, it's closer to children, This is not allowed, This kind of radioactivity may cause damage to every system, Because lactation is the same, Because mothers or pregnant women need to have close contact with their children, After all, radioactivity is a radioactive thing, Because children are still developing, There may be damage to all systems, Try not to use iodine 131 in pregnancy and lactation.
