彩色多普勒超声对甲状腺结节的定性诊断价值

Value of color Doppler ultrasound on qualitative diagnosis of thyroid nodule

目的探讨彩色多普勒超声对甲状腺结节定性诊断的应用价值。方法对128例经手术后病理证实为甲状腺恶性结节患者的彩色多普勒声像图进行分析整理,分析不同甲状腺疾病的声像图特征及与临床病理的符合率。结果结节性甲状腺肿患者彩超诊断21例,病理诊断23例,诊断符合率为91.3%,2例结节性甲状腺肿误诊为甲状腺腺瘤;甲状腺腺瘤病彩超诊断62例,病理诊断56例,诊断符合率为90.3%;甲状腺癌彩超诊断45例,病理诊断49例,诊断符合率为91.8%,4例甲状腺癌误诊为甲状腺腺瘤。结论超声检查简便、无创、可重复检查、随诊观察,是甲状腺检查的首选方法,对甲状腺结节的良恶性判断有重要价值。

Objective To explore the application value of color Doppler ultrasound on qualitative diagnosis of thyroid nodule. Methods The imagings of 128 cases of malignant nodule of thyroid diagnosed by pathology were analyzed and the coincidence rate between the ultrasound and the pathology was compared. Results Twenty-one patients of nodular goiter were diagnosed by ultrasound in twenty-three cases diagnosed by pathology, and the coincidence rate was 91.3%, the 2 cases of nodular goiter were misdiagnosed into thyroid adenoma. Fifty-six patients of thyroid adenoma were diagnosed by ultrasound in sixty-two cases diagnosed by pathology, and the coincidence rate was 90.3%. Forty- five patients of thyroid cancer were diagnosed by ultrasound in 49 cases diagnosed by pathology, and the coincidence rate was 91.8%, the 4 cases of thyroid cancer were misdiagnosed into thyroid adenoma. Conclusion Because of its ad- vantages, color Doppler ultrasound has the value of distinguishing the malignant in benign of thyroid nodule.
