利用放射性核素131I治疗弥漫性毒性甲状腺肿已经成为临床的主要方法之一。131I治疗剂量过小达不到治疗的目的 ,治疗剂量过大对患者和环境带来不必要的放射性暴露,特别是对于越来越多的年轻人接受放射性核素131I治疗,使131I导致的甲减对于患者生活质量的影响时间趋于长久。患者甲状腺体积(质量)是放射性核素131I治疗时计算投药量的重要参数,准确测量甲状腺体积是131I治疗的重要环节,也是评价疗效的有效指标之一。本文对甲状腺显像评估甲状腺体积的方法及影响因素进行综述。
The use of 131I for the treatment of diffuse toxic goiter has become one of the main clinical methods. 131I treatment dose is too small for the purpose of treatment, the treatment of excessive doses to patients and the environment caused unnecessary radioactive exposure, especially for more and more young people to accept 131I treatment of radionuclides, 131I led to a Minus influence on the quality of life of patients tend to be long. Thyroid volume (mass) of patients is an important parameter for calculating the dosage when 131I treatment of radionuclides. Accurate measurement of thyroid volume is an important part of 131I treatment and is also one of the effective indexes for evaluating the curative effect. This article reviews thyroid imaging to evaluate thyroid volume and its influencing factors.
