目的探讨超声血流多普勒与血清FT3、FT4对诊断Graves病的相关性。方法用血流多普勒超声检查对Graves病患者测量甲状腺上动脉舒张期内径、血流速度、阻力指数,并将检查结果与患者血清FT3、FT4检测结果进行相关性比较,同时与正常对照组比较。结果:Graves病患者超声血流多普勒检查所得双侧甲状腺上动脉的舒张期内径(D),收缩期最大血流速度(PSV),舒张末期血流速度(PDV)与甲状腺功能指标,尤其是FT4之间的呈一定相关性,相关系数为0.433～0.522。结论超声血流多普勒与血清FT3、FT4结合对诊断Graves病的定量诊断有一定价值。
Objective To investigate the correlation between ultrasonographic Doppler flow and serum FT3 and FT4 in the diagnosis of Graves disease. Methods The diastolic diameter, blood flow velocity and resistance index of the thyroid artery were measured by Doppler sonography in patients with Graves’ disease. The correlation between the results and the results of serum FT3 and FT4 was compared with that of the normal control group Compare Results: Diastolic diameter (D), systolic maximum flow velocity (PSV), end-diastolic flow velocity (PDV) and thyroid function indexes of bilateral thyroid artery obtained from Doppler ultrasound examination of Graves’ disease were Is a certain correlation between the FT4, the correlation coefficient of 0.433 ~ 0.522. Conclusion Ultrasound Doppler flow and serum FT3, FT4 in the diagnosis of Graves disease quantitative diagnosis of some value.
