应用放射性同位素~(131)碘研究甲状腺功能状态,是一种较新的诊断方法·这种方法就是使患者口服或静脉注射示踪量~(131)碘后,观测甲状腺摄取和浓聚~(131)碘的吸收率,以判断甲状腺的功能状态。目前,各处采用的测量方法,所用的探测器.使用的示踪剂量大小很不一致,诊断标准也不相同。例如,示踪量~(131)碘可以从1—2微居里以至数十微居里·探测技术,有用 r 计数管直接放在甲状腺部位进行测量,也有用闪砾探头或 r 计数管与颈部保持一定距离进行测
The use of radioactive isotope 131I iodine study of thyroid function status is a relatively new diagnostic method, this method is to make patients after oral or intravenous injection of 131I iodine, observe thyroid uptake and concentration ~ ( 131) iodine absorption rate, to determine the functional status of the thyroid. At present, the measurement methods used throughout, the detectors used, the amount of tracer used are very inconsistent, and the diagnostic criteria are not the same. For example, the amount of tracer 131I can range from 1-2 microcuries to tens of micro-Curie, which can be measured directly on the thyroid gland using the r-counting tube, Keep the neck at a distance
