超声检查和FNA诊断甲状腺结节的作用

Application of US and FNA in Diagnosis of Thyroid Nodules

流行病学研究显示甲状腺结节是常见的疾病。成人中约5%有甲状腺结节存在,其中约14.9%为恶性病变。近来超声技术被越来越广泛地应用于临床诊断甲状腺结节性疾病。细针吸取细胞学检查是一种甲状腺结节精确诊断的有效方法。本文重点介绍超声检查和细针吸取细胞学检查在甲状腺结节诊断中的作用概况。

Epidemiology studies suggest that nodular thyroid disease is a common clinical prob-lem. Palpable thyroid nodules occur in about 5 % of the population. Approximately 14.9 % of thyroid nodules are cancerous. The role for ultrasound （US） in the assessment of nodular thyroid disease has increased in recent years. Fine--needle aspiration （FNA） biopsy of the thyroid gland is an accurate diagnostic test used in the initial evaluation of nodular thyroid disease. In this paper, the application of ultrasonography and FNA in the diagnosis of thyroid nodules was introduced.
