• 摘要：

• 目的 探讨彩色多普勒超声技术在结节性甲状腺肿及甲状腺腺瘤诊断中的作用。方法 选取2015年2月至2017年8月浙江省绍兴市人民医院收治的110例经病理学诊断为甲状腺疾病的患者作为研究对象，根据病理学诊断结果将其分为A组（甲状腺腺瘤患者，54例）和B组（结节性甲状腺肿患者，56例），2组均进行彩色多普勒超声检查，对比诊断准确率、影像学特点及血流参数。结果 A组和B组彩色多普勒超声的诊断准确率比较［90.7%（49/54）比92.9%（52/56）］，差异无统计学意义（P＝0.955）。2组甲状腺肿大情况、结节数目、晕环、是否存在包膜比较，差异均有统计学意义（均P＜0.05）。血流信号分级结果 显示，A组血流信号Ⅱ级、Ⅲ级比例高于B组［38.9%（21/54）比5.4%（3/56）、27.8%（15/54）比3.6%（2/56）］，差异均有统计学意义（均P＜0.05）。脉冲多普勒血流频谱信号检测结果 显示，A组收缩期峰值流速高于B组［（6.6±1.2）cm/s比（6.3±2.5）cm/s］，舒张末期最低流速、阻力指数低于B组［（3.3±0.7）cm/s比（3.7±0.9）cm/s、（0.4±0.1）比（0.6±0.2）］，差异均有统计学意义（均P＜0.05）。结论 彩色多普勒超声技术在结节性甲状腺肿及甲状腺腺瘤诊断中的作用明显，准确性高。

• Objective To explore the role of color Doppler ultrasonography in the diagnosis of nodular goiter and thyroid adenoma. Methods A total of 110 patients with thyroid diseases confirmed by pathology admitted to Shaoxing People′s Hospital from February 2015 to August 2017 were selected. According to the diagnosis results, they were divided into group A (patients with thyroid adenoma, 54 cases) and group B (patients with nodular goiter, 56 cases). The two groups were examined by color Doppler ultrasonography. The diagnostic accuracy, imaging characteristics and blood flow parameters were compared between two groups. Results There was no significant difference in the diagnostic accuracy of color Doppler ultrasonography between group A and group B［90.7%（49/54） vs 92.9%（52/56），P＝0.955］; there were significant differences in goiter, number of nodules, acroteric halo and capsule between the two groups(all P＜0.05); the proportions of patients with grade Ⅱ and Ⅲ in group A were higher than those in group B［38.9%（21/54） vs 5.4%（3/56）, 27.8%（15/54） vs 3.6%（2/56）］ (both P＜0.05). The results of Doppler blood flow spectrum showed that peak systolic flow velocity in group A was higher than that in group B［（6.6±1.2）cm/s vs （6.3±2.5）cm/s］, minimum end-diastolic flow velocity and resistance index were lower than those in group B［（3.3±0.7）cm/s vs （3.7±0.9）cm/s, （0.4±0.1） vs （0.6±0.2）］(all P＜0.05). Conclusion Color Doppler ultrasound has a significant role in the diagnosis of nodular goiter and thyroid adenoma.
