高频超声对甲状腺癌诊断价值的临床研究

Clinical study on the value of high frequency ultrasound in diagnosis of thyroid carcinoma

目的:研究高频超声对甲状腺癌诊断价值的临床意义。方法:收治甲状腺癌患者158例,回顾性分析其高频超声及彩色多普勒的特征及血流特点。结果:在158例甲状腺癌中,甲状腺乳头状腺癌151例(95.57%),滤泡状腺癌4例(2.53%),髓样癌2例(1.27%),未分化癌1例(0.63%),诊断符合率94.32%。158例甲状腺癌中癌结节199个,低回声78.34%,微小结节中低回声出现率96.88%(93/96);所有癌结节中伴有钙化的108个(54.27%),微小钙化灶101个,伴有颈部淋巴结转移21例(13.29%)。结论:高频超声中出现钙化及低回声结节对甲状腺癌的诊断有重要价值。

Objective:To explore the value of high frequency ultrasound in diagnosis of thyroid carcinoma.Methods:158 patients with thyroid carcinoma were selected.Characteristics and flow characteristics of high frequency ultrasound and color doppler were retrospectively analyzed.Results:In 158 cases of thyroid carcinoma,151 cases(95.57%) were thyroid papillary adenocarcinoma;4 cases(2.53%) were follicular carcinoma;2 cases(1.27%) were medullary carcinoma;1 case(0.63%) was undifferentiated carcinoma;the diagnostic rate was 94.32% .In 158 cases of thyroid carcinoma,there were 199 cancer nodules;78.34% was low echo;the occurrence rate of low echo in tiny nodules was 96.88%(93/96).In all of the tumor nodules,108(54.27%) had calcification;101 had micro calcifications;21 cases(13.29%) had cervical lymph node metastasis.Conclusion:In high frequency ultrasound,calcification and hypoechoic nodules have important value for the diagnosis of thyroid carcinoma.
