声学密度技术在桥本氏甲状腺炎诊断中的应用

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

The Clinical Application of Acoustic Densitometry Technique in the Diagnosis to Hashimoto′s Thyroiditis

Objectives: To investigate the clinical diagnostic value of acoustic densitometry (AD) technique in detecting Hashimoto′s thyroiditis. Methods: The average values of integrated backscatter (IBS) of thyroid gland were acquired from 22 patients with Hashimoto′s thyroiditis and 32 normal people based on routine thyroid ultrasonography, and fine-needle aspiration biopsy were performed simultaneously. Results: Compared with normal people, the echoes of thyroid of patients are totally low and uneven and harsh; the sizes of those are obviously increasing. The average value of IBS in patients is significantly lower than that of normal people and their pathologic examinations show heavy infiltrations of lymphocytes. Conclusion: There is a characteristic change of AD in Hashimoto′s thyroiditis. Combined with traditional examinations, more information can be obtained and it will be helpful for diagnosis.
