甲状腺恶性结节的彩色多普勒超声的特征研究

摘要

目的：分析甲状腺恶性结节彩色多普勒超声特征，探讨彩色多普勒超声对甲状腺恶性结节的诊断价值.方法：收集近期在笔者所在医院选择手术治疗的甲状腺恶性结节患者79例，对其临床资料进行统计分析，回顾性分析甲状腺恶性结节彩色多普勒超声特征，探讨彩色多普勒超声对甲状腺恶性结节的诊断价值.结果：超声对甲状腺恶性结节的诊断率为72.2%，误诊率为27.8%；其中误诊为结节性甲状腺肿17例(77.3%)，甲状腺腺瘤3例(13.6%)，其他2例(9.1%).甲状腺恶性结节超声检查主要依赖于对结节形态特征的评价，主要包括：边界、回声、内部回声结构、钙化特点以及结节内部血流情况等，恶性结节的主要特点为边界不清、低回声、内部为实性结构、无钙化或微钙化、结节内部血流丰富.结论：彩色多普勒超声对于甲状腺恶性肿瘤的诊断具有一定的价值，根据各项超声检查特征进行综合分析可以提高诊断率.%　　Objective:To analyze the malignant thyroid nodules color Doppler ultrasound characteristics,to explore the value of color Doppler ultrasound in the diagnosis of malignant thyroid nodules.Method:Collected 79 cases of patients with malignant thyroid nodules recently in our hospital and analyzed the clinical statistical data,retrospective analysis of thyroid malignant nodules color Doppler ultrasound characteristics.Result:The diagnosis of malignant thyroid nodules rate of ultrasonography was 72.2%,the misdiagnosis rate was 27.8%;misdiagnosed as nodular goiter,in which 17 cases (77.3%),thyroid adenoma,3 cases(13.6%),and the other two cases(9.1%).Thyroid malignant nodules ultrasound depends on the evaluation of nodular morphological features including:the boundary echo,internal echo structure,calcification characteristics as well as nodular internal blood flow conditions,the main features of the malignant nodules ill-defined,hypoechoic,solid structure within the no calcification or microcalcification,rich of nodules internal blood flow.Conclusion:Color Doppler ultrasound has a certain value for the diagnosis of thyroid malignancy according to the ultrasound characteristics of a comprehensive analysis and can improve the diagnostic rate.
