甲状腺结节超声引导下细针抽吸诊断的影响因素

The factors influencing diagnosis in US-guided fine needle aspiration of thyroid nodule

随着超声技术的进展及检查应用的普及,甲状腺结节的检出率也逐年上升。超声引导下细针抽吸细胞学检查因具有对结节良恶性诊断的高敏感性与特异性、安全简便且并发症少等优点而成为术前诊断的主要依据,减少了一些不必要的手术。尽管细针抽吸细胞学检查的诊断率高、应用广泛,但仍存在一定的局限性,其中重要的一点是无法得到满意的标本。标本取材对细胞学检查结果有较大影响。现就影响标本取材满意度的因素及解决方案予以综述。

The detection rate of thyroid nodules is increasing year by year with the promotion of ultrasonic technology and the popularization of examination.Ultrasound-guided fine needle aspiration cytology(US-FNAC)has been the main preoperative diagnostic basis due to its high sensitivity and specificity,simplicity and safety,few complications and other advantages.US-FNAC also reduces some unnecessary surgeries.Although FNAC has high diagnostic rate and is widely used,it still has some limitations.One of the most important points is that no satisfactory specimens can be obtained.The collected samples have a great influence on the cytological examination results.The factors that influence the collection of satisfied specimens and the corresponding solutions are briefly summarized.
