目的探讨应用彩色多普勒超声诊断结节性甲状腺肿的临床价值。方法应用高频探头,对69例结节性甲状腺肿与33例甲状腺腺瘤患者进行彩色多普勒超声检查,对声像图表现进行分析,并应用脉冲多普勒进行血流动力学参数测定。结果结节性甲状腺肿的结节为多发,形态欠规则,边界欠清晰,部分有不完整包膜,无晕环,多伴有囊性变;结节周边及内部血供不丰富。甲状腺腺瘤常单发,形态规则,边界清楚,包膜完整,有晕环;结节周边及内部血供较丰富。结论彩色多普勒超声的应用有助于临床对结节性甲状腺肿的诊断。
Objective To investigate the clinical value of color Doppler sonography in the diagnosis of nodular goiter. Methods The color Doppler ultrasound was performed on 69 cases of nodular goiter and 33 cases of thyroid adenoma by using high frequency probe. The sonography was performed and the hemodynamic parameters were measured by pulsed Doppler. . Results nodular goiter nodules are multiple, irregular shape, the border is not clear, some incomplete envelopes, no halo, with cystic degeneration; peripheral and internal nodules blood supply is not rich. Thyroid adenoma often single, regular rules, clear boundaries, complete capsule, halo; peripheral and internal nodules more abundant. Conclusion The application of color Doppler ultrasound is helpful to the clinical diagnosis of nodular goiter.
