甲状腺癌的二维及彩色多普勒超声分析

Analysis of Two-dimensional and Color Doppler Ultrasonic Characteristics in Thyroid Carcinoma

目的探讨高频超声在甲状腺癌诊断中的应用价值。方法对经手术及病理证实的52例甲状腺癌及40例甲状腺腺瘤的二维及彩色多普勒(CDFI)超声表现进行分析比较。结果甲状腺癌表现的周边无声晕、低回声及微钙化灶检出率分别为82.69%,71.15%和59.60%,甲状腺癌的血供以高阻力为特征,与甲状腺腺瘤有显著性差异(P<0.01)。结论结合二维声像图及CDFI表现,将有助于提高甲状腺癌诊断的准确性。

Objective To evaluate the value of ultrasonography in the diagnosis of thyroid carcinoma. Methods Fifty-two cases with thyroid carcinoma and forty cases with thyroid adenoma, confirmed by pathology were analyzed comparatively with two-dimensional and color Doppler flow imaging （CDFI）.Results The ultrasonographic characteristics of thyroid carcinoma showed no halo sign in 82.69%, hypoechoic in 71.15% and microcalcification in 59.60%.CDFI showed rich blood signals with high resistance index in thyroid carcinoma. There were significant differences in two-dimensionalal image and CDFI between thyroid carcinoma and thyroid adenoma. Conclusions The ultrasonographic characteristics of the tumor are helpful for diagnosis of thyroid carcinoma.
