摘要
目的探讨超声检查对桥本氏病的诊断价值。方法回顾性分析经病理证实的23例桥本氏病患者的声像图特征,观察其血液T3、T4、TSH水平变化与声像图改变间的关系,并分析甲状腺上、下动脉峰值血流速度、阻力指数的变化在桥本氏病的鉴别诊断中的作用。结果桥本氏病患者中,除2例甲状腺体积减小外,其余病例甲状腺体积增大、形态不规则、包膜不光滑,腺体回声不均质,多见网格样条索状回声,内部可见低回声或低回声与强回声结节并存。彩色多普勒血流显像示:8.7%(2/23)的患者腺体内的血流信号明显减少,39.1%(9/23)的患者的腺体内血流信号增多,52.2%(12/23)的患者呈现典型的"火海征"。甲状腺上、下动脉的血流峰值速度显著高于对照组,而血流阻力指数无显著差异。结论超声检查是桥本氏病诊断和鉴别诊断的重要工具。
Objective To investigate the sonographic characters of Hashimoto thyroiditis and the diagnostic value of color Doppler ultrasound. Methods Twenty three patients with Hashimoto thyridifis confirmed by pathology were analyzed retrospectively about following aspects such as their sonographic characters, the blood levels of T3, T4, TSH and their relationship with the changes of sonographic characters, and also the changes of peak velocity （Vmax） and resistance index （RI） of superior and inferior thyroid artery. Retsults Of all these Hashimoto thyroiditis patients, there were enlarged and irregular thyroid gland with unsmoothed integument and hypoechoic nodules or a coexistence of hypoechoic/hyperechoic nodules, except 2 patients with shrinked thyroid gland. CDFI indicated that 8.7% （2/23） among these patients were with reduced blood signals, while 39.1%（9/23） with rich blood signals, and 52.2% （12/23） with typical sign as ＂conflagration＂. The peak velocity （Vmax） of superior and inferior thyroid artery were remarkably higher than that of control, however resistance index （RI） value was no significance. Conclusion Color Doppler ultrasound is of an important method in the diagnosis and differential diagnosis of Hashimoto thyroiditis.
