【摘要】 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:分析经手术后病理检查证实的52例甲状腺腺瘤患者的54个结节和78例结节性甲状腺肿患者的102个结节的声像图,对2组疾病的二维声图像与彩色多普勒血流显像图像特点进行比较分析。结果:2组疾病在发病年龄、性别、病灶部位、结节大小、结节退行性改变(钙化、囊性变或者出血)等方面差异均无统计学意义(P>0.05);在结节数目,结节形状,结节内实质回声,结节边界(晕环、包膜),结节内部、周边血流信号等方面差异均有统计学意义(P<0.05)。结论:甲状腺腺瘤和结节性甲状腺肿二者的病理基础不同,构成了超声图像上不同的特征,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。更多还原

【Abstract】 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 52 patients(54 lesions) with thyroid adenoma and 78 patients(102 lesions) 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 no significant differences in age,sex,location and size of lesions,degeneration of lesions(calcification,hemorrhage or cystic)(P>0.05).There were sitatistic differences in the number of lesions,the shape of lesions,the essence echoes in the intranodular,the border of lesions(halo sign,envelope),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.更多还原
