Abstract:Objective:To discuss the ultrasounic diagnosis progress in thyroid malignant nodules. Methods:To review the relevant literatures concerning of thyroid nodular about ultrasounic diagnosis and summarize, especially the malignant ones. Results:Ultrasonography can record the number,location,size,boundary,internal echo of thyroid malignant nodules. Combined with the relevant new technologies (such as ultrasound elasticity imaging, contrast-enhance ultrasound imaging), the diagnostic rate of malignant thyroid nodules could be improved.Conclusions:Timely and correct diagnosis can be obtained in thyroid malignant nodules by correctly mastering and analyzing the ultrasonographic characteristics so as to provide more decision-making information for the clinical procedures.
