不同年龄结节性甲状腺肿合并甲状腺癌患者甲状腺超声特征比较分析

Comparative analysis of ultrasound features of thyroid in different age patients with nodular goiter combined with thyroid carcinoma

目的探讨结节性甲状腺肿合并甲状腺癌不同年龄段患者甲状腺超声的图像特征。方法以2011年2月~2016年12月我院收治的60例结节性甲状腺肿合并甲状腺癌患者为研究对象,依据年龄不同分为青年组(年龄<40岁,31例)、中年组(年龄40~59岁,17例)和老年组(年龄≥60岁,12例)。3组患者均以二维超声和彩色多普勒进行甲状腺检查,对比观察3组超声图像回声、钙化、血流信号、SPV及RI。结果青年组病灶低回声率为78.5%,病灶微钙化率为86.2%,血流分型Ⅲ型构成比为89.7%,SPV为(31.04±2.17)cm/s,RI为(0.95±0.06)%,均显著高于中年组和老年组,差异有统计学意义(P<0.05)。结论不同年龄结节性甲状腺肿合并甲状腺癌患者的甲状腺超声图像特征存在差异,病灶低回声伴微小钙化、血流信号丰富、血流阻力大是青年患者的主要声像图表现。

Objective To study the nodular goiter complicated with thyroid cancer thyroid ultrasound image in patients with different ages.Methods60patients with nodular goiter complicated with thyroid cancer were treated for the study from Feb2011to Dec2016in our hospital,depending on the age into youth group(<40years of age,31cases),middle age group(ages40~59years old,17cases)and aged group(≥60years of age,12cases).Three groups of patients were based on two dimension ultrasound and color doppler thyroid examination,comparison of three echoes,calcification,ultrasound blood flow signal,SPV and RI.Results The low echo rate in the youth group was78.5%,the micro calcification rate of lesions was86.2%,the typeⅢcomposition of blood flow type was89.7%,SPV was(31.04±2.17)cm/s and RI was(0.95±0.06)%,the indexes were significantly higher than those in middle age group and aged group,and the difference was statistically significant(P<0.05).Conclusion There were differences in thyroid ultrasonographic features in patients with nodular goiter and thyroid carcinoma at different ages,focal keyed sound with small calcification,abundant blood flow signal and large blood flow resistance are the main sonographic manifestations of young patients.
