目前,儿童甲状腺峡部的厚度(即峡部前后径)已成为人们关注的焦点问题,在中国十大城市学龄儿童碘营养状况调查中发现,有7个城市学龄儿童的甲状腺触诊肿大率高于B超肿大率。现实行的甲状腺触诊方法中,甲状腺的厚度,尤其是峡部厚度,是影响触诊准确性的重要因素之一,而WHO/UNICEF/ICCIDD制订的儿童少年甲状腺B超正常值标准中的甲状腺体积,没有包括峡部体积,只是两侧叶的体积之和。那么,儿童甲状腺峡部的厚度对 At present, the thickness of thyroid isthmus in children (ie isthmus anteroposterior diameter) has become the focus of attention. In a survey of iodine nutrition status of school-age children in ten Chinese cities, thyroid palpation and esophageal enlargement rate in school-aged children in seven cities B super-enlargement rate. The actual thyroid palpation method, the thyroid thickness, especially isthmus thickness, is one of the important factors affecting palpation accuracy, and WHO / UNICEF / ICCIDD developed children’s thyroid B-normal value of the thyroid volume , Does not include isthmus volume, but the sum of the volume of the leaves on both sides. Well, the thickness of the thyroid isthmus in children is right
