超声对甲状腺腺瘤与结节性甲状腺肿的鉴别诊断

目的：探讨二维超声及彩色多普勒血流显像对甲状腺腺瘤和结节性甲状腺肿的鉴别诊断价值。方法：回顾分析术后经病理证实的25例甲状腺腺瘤和30例结节性甲状腺肿患者的超声声像图,并对两组病例的二维声像图和彩色多普勒血流图像特点进行比较分析。结果：两组疾病在结节数目、晕环有无、包膜有无、结节内部、周边血流信号等方面比较差异均有统计学意义（P〈0.05）。结论：由于甲状腺腺瘤和结节性甲状腺肿之间的病理基础不同,从而形成了超声声像图上的特征性改变,可作为甲状腺腺瘤和结节性甲状腺肿的超声鉴别诊断要点。

Ultrasonography in differential diagnosis of thyroid adenoma and nodular goiter

Objective：To discuss the diagnostic value of 2-dimensional and color Doppler flow imaging ultrasonography to the differential diagnosis of thyroid adenoma and nodular goiter.Methods：The ultrasonography materials were analyzed in 25 patients with thyroid adenoma and 30 patients with nodular goiter confirmed by postoperative pathologic examinations.The characteristics of images of 2-dimensional ultrasonography and color Doppler flow imaging were compared and analyzed.Results：There were sitatistic differences in the number of lesions,the halo sign of lesions,envelope of lesions,internal blood flow and perinodular blood flow（P〈0.05）.Conclusion：The pathologic basis of thyroid adenoma and nodular goiter are different,and they have their own ultrasonographic characteristics.Ultrasonography can be used to make differential diagnosis,between two kinds of diseases.
