Abstract    Fine-needle aspiration (FNA) is one of most important procedures in diagnosing thyroid nodules because of its convenience，safety，minimal invasion and fast. The American Thyroid Associations recommends FNA as the most accurate and cost-effective method for evaluating thyroid nodules. It is considered to be gold standard of initial diagnosis in thyroid nodules. Ultrasound-guided FNA utilizes real-time US to localize the needle tip in the target nodule correctly，which improves the accuracy of biopsy and reduces the rate of false-negative.

Key words: ultrasound-guided fine-needle aspiration, thyroid nodule

摘要：

细针穿刺抽吸活检（fine-needle aspiration，FNA）是甲状腺结节诊断过程中非常重要的步骤之一，其操作方便、安全、微创，诊断快速，被美国甲状腺协会（ATA）推荐作为甲状腺结节诊断中成本-效益最佳的方法，可视为初诊甲状腺结节筛查的金标准。超声引导下细针穿刺抽吸活检（US-FNA）利用实时超声定位，能精确穿刺针的针尖位置，大大提高了穿刺的准确性，可有效降低假阴性率。
