摘要
目的探讨桥本甲状腺炎(HT)超声声像图特征及其鉴别诊断。方法回顾性分析40例经病理证实为桥本甲状腺炎患者的甲状腺超声声像图特征:二维条件下甲状腺大小、实质回声;彩色多普勒条件下腺体血流分布情况;频谱多普勒条件下甲状腺上动脉峰值流速(PSV)。结果甲状腺明显增大,峡部明显增厚者87.5%(35/40);实质回声弥漫性减低者80%(32/40),局限性减低者20%(8/40);实质回声呈网格状改变者90%(36/40),伴单发或多发结节者10%(4/40);血流信号丰富呈"火海"征37.5%(15/40),血流信号稍增多50%(20/40),血流信号不明显或仅浅表1/3范围内有血流信号分布12.5%(5/40);甲状腺上动脉峰值流速(PSV)显著高于对照组;本次研究超声诊断符合率95%。结论超声对桥本甲状腺炎有很高的诊断符合率,可作为HT临床诊断的首选影像学检查方法。
Objective To explore the features and differential diagnosis of Hashimoto＇s thyroiditis （HT）. Methods We retrospectively analyzed 40 patients with pathologically confirmed Hashimoto＇s thyroiditis in patients with thyroid sonographic features of thyroid size： two-dimensional conditions, the real echo; color Doppler glands under conditions of blood flow distribution; spectrum DhoopLe conditions thyroid artery peak flow velocity （PSV）. Results Thyroid was significantly increased and marked thickening of the isthmus accounted for 87~% （35/40）; parenchyma echo diffuse reduction accounted for 80% （32/40）, limitations reduce accounted for 20% （8/40）; parenchyma echo is accounted for 90% of the grid changes （36/40）, with single or multiple nodules in 10% （4/40）; blood flow signal was the ＂sea of fire levy ＂ accounted for 37.5% （15/40）, the flow signal is slightly increased accounted for 50%（20/40）, flow signal is not obvious or only superficial blood flow signals in the range of 1/3 accounted for 12.5% （5/40）; thyroid artery peak velocity （PSV） was significantly higher; Ultrasonic diagnosis rate has reached 95% in this study. Conclusion Ultrasound Hashimoto＇s thyroiditis has a high diagnostic accuracy, the examination method can be used as the preferred image of the HT clinical diagnosis.
