摘要
目的 评价灰阶和彩色多普勒超声在甲状腺癌诊断中的作用。方法 分析经手术及病理证实 89例甲状腺癌的 98个病灶的灰阶及彩色多普勒声像图表现。结果 所有甲状腺癌肿超声显示 5 9.1% (5 8/ 98)边界不清 ,76.5 % (75 / 98)低回声或稍低回声 ,76.5 % (75 / 98)内部回声不均 ,88.8% (87/ 98)无暗环 ,46.9% (4 6/ 98)内部出现微钙化点 ,95 .9% (94/98)无液化 ,63 .6% (14 / 2 2 )内部出现丰富动脉血流 ,85 .7% (18/ 2 1)阻力指数RI≥ 0 .70。结论 根据肿瘤灰阶及彩色多普勒超声的特征性表现 。
Purpose To evaluate the value of ultrasonography in diagnosis of thyroid carcinoma. Methods Eighty nine patients with 98 lesions confirmed by operation and pathology. The tumor characteristics of thyroid in gray scale and color Doppler flow imaging (CDFI) were depicted. Results The ultrasonographic texture of all the lesions showed that there were unclear margin in 59.1%(58/98), hypoechoic pattern in 76.5%(75/98), inhomogeneity in 76.5%(75/98), absence of halo sign in 88.8%(87/98), microcalcification in 46.9%(46/98), no cystic degeneration in 95.9%(94/98). CDFI showed rich blood signal in 63.6%(14/22), resistance index RI≥0.70 in 85.7(18/21).Conclusion The ultrasonographic characteristics of tumor are helpful in diagnosis of thyroid carcinoma.
