近年来，超声检测儿童甲状腺容积仍然存在一些争议，主要集中于不同检测人员、检测仪器和检测技术等导致的测量误差，以及随着儿童的发育水平不断提高，生理因素对甲状腺容积的影响和相关的校正方法。因此，本文对国内外文献进行了综述，首先，通过描述国际推荐甲状腺容积参考值和各国与我国的参考值，明确了各自甲状腺容积标准值的差异，分析了各自的现状和特点；其次，通过研究超声检测方法与生理因素对甲状腺容积测量值的影响，分析了各种因素重要性的大小，讨论了几种测量方法的可用性，进行了几种甲状腺容积校正方法的对比，为进一步完善我国儿童甲状腺容积标准值提供建议。“,”The controversy over the ultrasonic testing of thyroid volume (TVOL) in children exists in some aspects, mainly focusing on the measurement errors caused by different testing personnel, instruments and techniques. Moreover, with the development of children growth higher than before, the influence of physiological factors on TVOL and relevant correction methods should be paid attention. This paper reviews domestic and foreign literatures. Firstly, through describing the TVOL reference values of international recommended, foreign country and China, we clarify the differences between them, and analyze the current situation and characteristics of each. Secondly, by studying the ultrasonic testing methods and physiological factors which affect TVOL, this paper analyzes the importance of various factors, discusses the availability of several measurement methods and compares several TVOL correction methods. Some suggestions are put forward for further improving the reference value of TVOL of children in China.
