目的 :探讨声学密度 ( AD)技术在桥本氏甲状腺炎检测中的应用价值。方法 :在常规超声检查的基础上 ,测量 2 2名桥本氏甲状腺炎患者及 32名正常人的甲状腺实质背向散射积分 ( IBS)值 ,并进行同期甲状腺穿刺活检。结果 :桥本氏甲状腺炎患者回声普遍偏低 ,不均匀 ,IBS值明显低于正常人 ( P<0 .0 0 1 ) ,甲状腺明显大于正常人 ( P<0 .0 1～ P<0 .0 0 1 )。结论 :桥本氏甲状腺炎患者在 AD检查中有特征性变化 ,可提供更多的信息 ,有利于诊断 Objective: To investigate the value of acoustical density (AD) technique in the detection of Hashimoto’s thyroiditis. Methods: Thyroid solid backscatter integral (IBS) values ​​of 22 Hashimoto’s thyroiditis patients and 32 normal subjects were measured and routine thyroid needle biopsy was performed on the basis of routine ultrasound examination. Results: The echoes of Hashimoto’s thyroiditis were generally low and uneven, the IBS value was significantly lower than that of normal people (P <0.01), and the thyroid gland was significantly larger than that of normal people (P <0.01 ~ P <0.01). 0 0 1). Conclusions: Hashimoto’s thyroiditis patients have characteristic changes in AD examination, which can provide more information, which is helpful for diagnosis
