原发性甲亢的高频及多普勒超声表现

High Frequency and Doppler ultrasonographic characteristic of original Hyperthyroidism

目的 探讨高频及多普勒超声对原发性甲状腺机能亢进 (Graves病 )的诊断价值。方法 对 171例Graves病患者及 5 0例正常人行高频及多普勒超声检查 ,并结合T3、T4结果进行分析。结果 甲亢患者甲状腺三维径值及容积显著增大 ,与对照组比差异显著 (P <0 .0 5 ) ,腺体回声增粗增强 ,血流信号增多 ,甲状腺上动脉收缩期峰值流速及阻力指数增高 ,与血T3、T4升高呈正相关 (r =0 .91,γ值经假设检验P <0 .0 1)。

Objective To explore the value of high frequency and Doppler ultrasonography in diagnosis of original hyperthyroidism.Methods High frequency and Doppler ultrasonography were performed on 171 cases of hyperthyroidism and 50 normal persons.The results of ultrasound and T 3?T 4 were studied comparatively.Results In patient's group,the length,width,depth and volume of the thyroid were significantly increased.Color signals showed abound in a diffuse hyperechoic gland,and the end-systole flow velocity and resistant index of the superior thyroid artery rised,which were highly related to T 3?T 4(r=0.91,P<0.01).Conclusions High frequency ultrasonography combining with Doppler ultrasonography is valuable in diagnosis of original hyperthyroidism.
