对253名受试者（130名女性和123名男性;年龄范围，19-50岁）进行了甲状腺高频超声检查，这些受试者是从芬兰甲状腺肿不流行的地区的人群中随机选择的。甲状腺回声异常69例（27.3%）。异常的患病率随着年龄的增长而增加，在这30年中，女性比男性表现出更多的病变。39例受试者（57%）的异常为孤立性，15例（22%）为多发性，15例（22%）为弥漫性。在68个单个结节中，48个（70%）直径小于1 cm。在28例受试者中发现直径1-5 mm的无回声圆形结节。对30例受试者进行了细针穿刺活检。细胞学检查未发现明确的恶性肿瘤。在8例（3.2%）弥漫性回声异常的受试者中，细胞学评价提示淋巴细胞性甲状腺炎。它的结论是，在一个随机选择的成年人群中，甲状腺小回声异常的患病率是相当高的，一个事实，支持使用保守的方法，这些类型的结果。
High-frequency ultrasound examination of the thyroid was performed in 253 subjects (130 women and 123 men; age range, 19-50 years) that were randomly selected from the population in an area of Finland where goiter is not endemic. Thyroid echo abnormalities were detected in 69 subjects (27.3%). Prevalence of abnormalities increased with age, and women showed more lesions than did men in each of the 3 decades. The abnormality was solitary in 39 subjects (57%), multiple in 15 (22%), and diffuse in 15 (22%). Of the 68 individual nodules, 48 (70%) were smaller than 1 cm in diameter. Anechoic rounded nodules 1-5 mm in diameter were found in 28 subjects. Fine-needle aspiration biopsy was performed in 30 subjects. Cytologic examination revealed no unequivocal malignancies. In eight subjects (3.2%) with a diffuse echo abnormality, cytologic evaluation indicated lymphocytic thyroiditis. It is concluded that the prevalence of small thyroid echo abnormalities in a randomly selected adult population is rather high, a fact that supports use of a conservative approach to these types of findings.
