摘要
目的:探讨高频超声在甲状腺良恶性结节鉴别诊断中的应用价值。方法:经病理证实的123例患者的179个甲状腺结节术前经超声常规检查,回顾分析甲状腺结节声像图特征,并进行统计学分析。结果:甲状腺的良性结节142个:120个形态规整,117个边界清晰,135个无钙化或见粗大钙化,126个等回声或高回声,96个结节内部无明显血流或血流信号较稀少。甲状腺的恶性结节37个:22个形态不规则,26个边界不清晰,28个低回声,14个见微小钙化,26个结节的内部血流信号分布范围达1/3以上。结论:甲状腺结节的边界、形态、钙化及结节内的血流分布情况有助于良恶性鉴别。
Objective： To explore application value of high-frequency ultrasound in diagnosis of benign and malignant thyroid nodules. Methods： 179 nodules of 123 patients were preoperatively confirmed by pathology after routine ultrasound examination,and the nodules ultrasonographic features were reviewed and statistically analyzed. Results： 142 Benign nodules： 120 had regular shape,117 had clear boundary,135 had no calcification or macro- calcification,162 had equal echo or high echo,and 96 had no obvious blood flow in them or blood flow signal was relatively rare. 37 Malignant nodules： the shape of 26 was irregular,the boundary of 22 was not clear,28 had low echo,14 had tiny calcification,and the internal blood flow signal distribution of 26 nodules covered more than a third. Conclusions： Thyroid nodules＇ boundary,shape,calcification and blood flow distribution within the nodules contribute to identification of benign and malignant nodules.
