弥漫性甲状腺肿大的彩色多普勒超声鉴别

Differential Diagnosis of Diffuse Thyroid Enlargement by Color Doppler Ultrasonic Technique

目的 :评价彩色多普勒超声鉴别诊断弥漫性甲状腺肿大的价值。材料与方法 :15 3例弥漫性甲状腺肿大患者 ,根据临床诊断分为 :甲状腺机能亢进 (甲亢 )组 ,单纯性甲状腺肿大组 ,甲状腺炎组和正常对照组 ,以彩色多普勒超声检查观察两侧甲状腺的血流分布情况 ,测定甲状腺上动脉的内径、收缩期峰值、阻力指数和血流量进行对比分析。结果 :甲状腺不同病变其血流信号及血流参数各不相同。结论 :彩色多普勒超声对弥漫性甲状腺肿大具有鉴别诊断价值。

Purpose: To evaluate the impact of color Doppler technique on differential diagnosis of diffuse goiter. Materials and Method: 153 patients with diffuse goiter were classified into four groups (hyper thyroidism, simple goiter, thyroiditis and normal control), Comparitive analysis as made based on parameters as the distributions of the thyroid blood flow, the inner diameter of superior thyroid artery, the systolic peak blood flow, and the esistance index, which were all obtained by color Doppler examination. Results: Different thyroid diseases were found to have with different blood flow signs and blood flow paramenter. Conclusion: Color Doppler examination has important value in the diagnosis of diffuse goiter.
