目的探讨二维及彩色多普勒血流成像(CDFI)对结节性甲状腺肿的诊断价值。方法分析44例临床明确诊断的结节性甲状腺肿患者89个结节的二维及彩色多普勒超声声像图特征。结果等回声或低回声结节12个,无回声结节11个,混合性回声结节66个,25个结节内可见到稍增多的点线状血流信号。结论结节性甲状腺肿的超声图像有一定的特异性,在诊断与鉴别诊断上具有重要价值。
Objective To investigate the diagnostic value of two-dimensional and color Doppler flow imaging (CDFI) for nodular goiter. Methods Two-dimensional and color Doppler ultrasonographic features of 89 nodules in 44 clinically diagnosed nodular goiters were analyzed. Results such as echogenic or hypoechoic nodules 12, 11 non-echogenic nodules, mixed echogenic nodules 66, 25 nodules can be seen slightly increased dot linear blood flow signal. Conclusion Nodular goiter ultrasound images have a certain specificity, in the diagnosis and differential diagnosis of great value.
