摘　　要：目的　探讨脉冲多普勒对亚临床甲状腺功能低下和甲状腺功能亢进的鉴别诊断价值。方法　应用彩色多普勒和脉冲多普勒技术检查 12例亚临床甲状腺功能低下和 2 3例甲状腺功能亢进患者 ,测量双侧甲状腺上动脉的收缩期最大血流速度、舒张期末最低流速和阻力指数 ,用统计学方法进行分析。结果　甲状腺功能亢进患者的甲状腺上动脉各项血流动力学指标均高于亚临床甲状腺功能低下者 ,经 t检验 ,2种疾病各项指标间差异均有显著意义 (P <0 .0 1)。左、右侧甲状腺上动脉收缩期最大血流速度 t值分别为 3.2 2 0 ,2 85 9;舒张期末最低流速 t值为 2 .80 6 ,2 .94 1;阻力指数为 4 .192 ,3.2 73。应用脉冲多普勒技术诊断亚临床甲状腺功能低下的准确率为83.33% ;诊断甲状腺功能亢进的准确率为 91.30 %。结论　脉冲多普勒不但能诊断亚临床甲状腺功能低下和甲状腺功能亢进 ,而且是鉴别此Objective To investigate the clinical value of pulse Doppler teehnique for the differentiating diagnosis between subcinical hypothyroidism and hyperthyroidism.Methods Examinations were performed with color Doppler and pulse Doppler teehnique for 12 cases of subcinical hypothyroidism and 23 cases of hyperthyroidism.We measured peak systalic vclocity,end diastolic velocity and resistive index of bilateral superior thyroid artery.These data were tested by statistic method.Results All indexes of superior thyroid artery in hyperthyroidism.There were significant differences between hypothyroidism and hyperthyroidism by T test,P<0.01.The T values of peak systalic velocity,end diastalic velocity and resistive index of the and right superior thyroid artery were 3.220,285;2.806,2.94;4.192,3.273.In diaghosing subcinical hypothyroidism and hyperthyroidism with pulse Doppler technique,its accurate rate were 83.33% and 91.3%.Conclusions Pulse Doppler not only can diagnose subclinical hypothyroidism and hyperthyroidism,but also was a reliable method in differentiatiog these two diseases.
