目的 :探讨二维及彩色多普勒超声对结节性甲状腺肿的诊断价值。方法 :采用二维及彩色多普勒超声对 37例 ( 76个结节 )经手术病理证实的结节性甲状腺肿患者进行检查。用彩色多普勒血流显像对甲状腺上动脉的血流动力学参数进行测定 ;分级评价结节内部及周边的彩色血流图。结果 :结节性甲状腺肿结节多为多发 ,大部分边界清楚 ,形态规则 ,无晕环 ,多数伴有囊性变或钙化。结节囊性变者甲状腺上动脉血流参数与正常组比较 ,无统计学意义 ( p>0 .0 5 )。结节内部及周边血供不丰富。结论 :二维及彩色多普勒超声有助于临床对结节性甲状腺肿的诊断 Objective : To investigate the diagnostic value of two-dimensional and color Doppler ultrasound in the diagnosis of nodular goiter. METHODS: Two-dimensional and color Doppler ultrasonography were used to examine 37 cases (76 nodules) of patients with nodular goiter confirmed by pathology. The hemodynamic parameters of the superior thyroid artery were measured by color Doppler flow imaging; graded blood flow patterns within and around the nodule were evaluated. RESULTS: Nodular goiter nodules were mostly multiple, most of the borders were clear, the morphology was regular, there was no halo ring, and most of them had cystic degeneration or calcification. The blood flow parameters of the superior thyroid artery in nodular cystic changes were not statistically significant (p>0.05). Blood supply is not abundant within and around the nodules. Conclusion : Two-dimensional and color Doppler ultrasound is helpful to the diagnosis of nodular goiter
