本文的目的是用超声波来测量芬兰北部13岁学龄儿童的甲状腺体积和回声类型。在1990年1—2月间,作者用带有7.5MHz 线性探头的真时扫描器,以直接接触法对76名健康学龄儿童进行了颈部超声检查。甲状腺每叶的体积按椭圆公式计算,即最大厚度×最大宽度 The purpose of this article is to use ultrasound to measure thyroid volume and echo type in a 13-year-old school-age child in northern Finland. From January to February 1990, the author used a real-time scanner with a 7.5 MHz linear probe to perform neck ultrasonography on 76 healthy school-age children by direct contact. The volume of thyroid per leaf is calculated by the ellipse formula, ie maximum thickness × maximum width
