目的探讨不同超声声像图特征对直径≤2 cm的甲状腺良恶性小结节鉴别诊断价值.方法回顾性分析云南省肿瘤医院经手术病理确诊的150例患者168个最大径线均≤2 cm甲状腺结节.对其超声声像图特征进行统计学赋值,并进行二分类Logistic回归分析,建立Logistic回归模型,依据OR值对各特征的危险度进行排序.结果以结节内有微钙化、包膜无或不完整、结节内部呈实质性低回声、后方回声衰减、周边声晕不完整或缺失、结节内部以中心型供血为主、纵横比≥1、边界不清8个超声声像图特征对诊断最大径线≤2 cm甲状腺结节的Logistic回归模型有助于鉴别甲状腺良恶性小结节,OR值分别为9.581、8.751、8.552、7.919、6.198、5.873、5.484、4.867.结论甲状腺小结节不同超声声像图特征对甲状腺良恶性小结节鉴别诊断具有不同价值,综合评估有利于正确诊断.

Objective To explore sonographic features in the differentiation of benign and malignant thyroid nodules with maximum diameter ≤2 cm.Methods A total of 168 thyroid nodules with maximum diameter ≤2 cm in 150 pathologically confirmed cases were retrospectively analyzed .Using Logistic regression analysis,the OR values of all features were obtained .Results Some sonographic features were helpful to differentiate between benign and malignant small thyroid nodules , including microcalcification, no or incomplete capsule,hypoechogenecity,posterior acoustic attenuation ,no halo,central vascularity,taller-than-wide shape,unclear boundary.Their OR values were 9.581,8.751,8.552,7.919,6.198,5.873,5.484,and 4.867 respectively.Conclusion Ultrasound plays an important role in the diagnosis of thyroid nodules .
