桥本甲状腺炎与甲状腺机能亢进的超声鉴别诊断分析

Differential diagnosis of Hashimoto's thyroiditis and hyperthyroidism by ultrasonography

目的:探讨超声检查对桥本甲状腺炎与甲状腺功能亢进的鉴别作用。方法:将42例桥本甲状腺炎患者与45例甲状腺机能亢进患者分别作为对照组与观察组,依次对两组患者进行超声检查,观察不同疾病患者的超声表现,并记录其病变部位动脉中的血流阻力指数(RI)、收缩期峰值流速(PSV)与舒张末期流速(EDV)。结果:观察组患者的甲状腺上下径增大检出率明显高于对照组,而对照组患者的甲状腺峡部增厚、合并甲状腺结节、具有内部网格样回声以及颈部Ⅳ区与Ⅵ区淋巴结肿大检出率明显高于观察组,均具有统计学意义(P<0.05)。同时,观察组患者的PSV与EDV指标均明显高于对照组,具有统计学意义(P<0.05)。结论:超声检查对桥本甲状腺炎与甲状腺机能亢进有良好的鉴别诊断作用。

Objective To discuss the differential diagnosis of Hashimoto＇ s thyroiditis and hyperthyroidism by ultrasonography. Method 42 patients with Hashimoto＇s thyroiditis and 45 patients with hyperthyroidism were served as the control group and the observation group,respectively. The patients of two groups were examined by ultrasonography. The ultrasonic manifestations of patients with different diseases were observed. The resistance index（RI）,peak systolic velocity（PSV） and end diastolic velocity（EDV） of the arteries were recorded. Results The detection rate of thyroid enlargement in the observation group was significantly higher than that in the control group（P〈0. 05）. The thyroid isthmus thickening,thyroid nodules,internal grid like echo,and the detection rate of lymph node enlargement in the neck region Ⅳ and Ⅵ in the control group were significantly higher than those in the observation group（P〈0. 05）. The PSV and EDV in the observation group were significantly higher than those in the control group（P〈0. 05）. Conclusion Ultrasonography has a good differential diagnostic role in Hashimoto＇s thyroiditis and hyperthyroidism.
