摘要
目的探讨超声显像对良、恶性甲状腺结节的诊断价值。方法回顾性分析2008年1月~2011年12月本院收治甲状腺结节患者143例161个结节的超声表现,观察结节内部回声、微钙化、边界、形态和纵横比。结果恶性甲状腺结节超声主要表现为低回声、微钙化、边界不清、形态不规则、纵横比≥1。良、恶性甲状腺结节超声差异具有统计学意义（P〈0.01）。上述超声特征对诊断恶性甲状腺结节的特异度为75%~92%,灵敏度为53%~74%。结论良、恶性甲状腺结节超声显像具有特征性表现,超声检查对甲状腺良、恶性结节鉴别诊断具有重要意义。
Objective To investigate the value of ultrasonography in diagnosing benign and malignant thyroid nodules.Methods The ultrasonography data of 143 patients with 161 thyroid nodules from our hospital between January 2008 and December 2011 were retrospectively analyzed.Internal echoes,microcalcification,border,shape and anteroposterior to transverse diameter ratio（A/T） were observed.Results The ultrasound findings of malignant thyroid nodules were hypoechogenicity,microcalcification,ill-defined edge,irregular shape and A/T≥1,which were statistically different between benign and malignant thyroid nodules（P0.01）.The sensitivity and specificity of above ultrasound findings were 75%-92% and 53%-74% respectively.Conclusion Ultrasonography of malignant thyroid nodules has its own characteristics.Ultrasonography plays an important role in diagnosing benign and malignant thyroid nodules.
