Thyroid disorders are frequently seen in the community. Thyroid ultrasonography (US) is commonly used in the diagnosis of thyroid diseases. The relationship between heterogeneous echogenicity of thyroid gland and thyroid tests are well known.
The aim of this study is to evaluate the correlation of normal US with the thyroid tests. A total of 681 individuals were enrolled in the study. Individuals were separated into two groups as normal (group 1) and hypoechoic (group 2) according to the echogenicity in US. Subjects with nodular thyroid lesions were excluded from the study. Thyroid stimulating hormone (TSH), free T4 (fT4), thyroid peroxidase antibody (TPOAb) and anti-thyroglobulin antibody (TgAb) values were recorded in both groups and thyroid stimulating hormone receptor antibody (TRAb) was recorded in individuals with low TSH.
86.1% of individuals in group 1 had normal TSH, 93.7% had normal thyroid antibodies and in 77.6% of individuals, all thyroid tests performed were normal. In the 6.9% of the group 2, all reviewed thyroid tests were normal (P<0.001).
Our study shows that US is correlated with normal thyroid function tests and is a valuable tool in the prediction of normal thyroid function.
甲状腺疾病在社区中较为常见。甲状腺超声检查（US）常用于甲状腺疾病的诊断。甲状腺腺体回声不均匀与甲状腺检查之间的关系已为人所知。
本研究的目的是评估正常超声检查结果与甲状腺检查之间的相关性。共有681名个体参与了该研究。根据超声检查中的回声情况，个体被分为两组，即正常组（第1组）和低回声组（第2组）。甲状腺有结节性病变的受试者被排除在研究之外。记录两组的促甲状腺激素（TSH）、游离T4（fT4）、甲状腺过氧化物酶抗体（TPOAb）和抗甲状腺球蛋白抗体（TgAb）值，对于TSH值低的个体记录促甲状腺激素受体抗体（TRAb）。
第1组中86.1%的个体TSH正常，93.7%的个体甲状腺抗体正常，77.6%的个体所有进行的甲状腺检查均正常。在第2组中，6.9%的个体所有复查的甲状腺检查均正常（P<0.001）。
我们的研究表明，超声检查与正常甲状腺功能检查相关，是预测正常甲状腺功能的一种有价值的工具。
