| 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59.1%(58/98)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%(46/98)内部出现微钙化点,95.9%(94/98)无液化,63.6%(14/22)内部出现丰富动脉血流,85.7%(18/21)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,有助于甲状腺癌的正确诊断。 |

| 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. |
