To determine the relationship between thyroid blood flow and anthropometric measurements, pubertal stage, and thyroid and gonadotropic hormones.
We examined 123 healthy school-aged children prospectively (69 boys (56.1%) and 54 girls (43.9%), 7-17 years old). Their sex, age, body weight, height, body mass index (BMI), and pubertal stage were determined. Serum thyrotropin, free thyroxine, luteinizing hormone, and follicle stimulating hormone were measured in both genders, along with testosterone in boys and estradiol in girls. The peak systolic velocity (PSV), resistance index (RI), and pulsatility index (PI) of the superior thyroid artery were determined. The correlations between the Doppler parameters and these factors were investigated.
There were no differences in age, weight, height, BMI, thyroid volume, PSV, RI, or PI between boys and girls (P>0.05). The PSV and PI showed strong correlations with age, height, weight, puberty stage, thyroid volume, and BMI. The RI showed a strong inverse correlation with age, height, weight, puberty stage, and thyroid volume and a weak inverse correlation with the BMI.
Determination of the thyroid arterial flow in normal healthy children is important during a Doppler ultrasound (US) examination. Doppler US parameters and their percentiles should be described in healthy children from different age groups, and these percentiles will aid in interpreting Doppler US in children.
确定甲状腺血流与人体测量指标、青春期阶段以及甲状腺和促性腺激素之间的关系。
我们对123名健康学龄儿童进行了前瞻性研究（69名男孩（56.1%）和54名女孩（43.9%），年龄在7至17岁之间）。确定了他们的性别、年龄、体重、身高、体重指数（BMI）和青春期阶段。测量了男女的血清促甲状腺激素、游离甲状腺素、促黄体生成素和促卵泡激素，以及男孩的睾酮和女孩的雌二醇。测定了甲状腺上动脉的收缩期峰值流速（PSV）、阻力指数（RI）和搏动指数（PI）。研究了多普勒参数与这些因素之间的相关性。
男孩和女孩在年龄、体重、身高、BMI、甲状腺体积、PSV、RI或PI方面没有差异（P>0.05）。PSV和PI与年龄、身高、体重、青春期阶段、甲状腺体积和BMI呈强相关性。RI与年龄、身高、体重、青春期阶段和甲状腺体积呈强负相关，与BMI呈弱负相关。
在多普勒超声（US）检查中，测定正常健康儿童的甲状腺动脉血流很重要。应描述不同年龄组健康儿童的多普勒超声参数及其百分位数，这些百分位数将有助于解读儿童的多普勒超声检查结果。
