摘　　要：为了探讨彩色多普勒（CDFI）对亚临床甲状腺功能低下的诊断作用，本文报告42例经临床及实验室检查证实的亚临床甲状腺功能低下的CDFI检查结果，并与30例正常人对照，前者甲状腺体积弥漫性增大腺体内血流信号明显增多，出现类似于甲亢的CDFI表现。甲状腺上动脉内径增宽，其内血流速度增快，其收缩期峰速，舒张期末流速及时间平均最高流速等各测值均明显高于正常组（P＜0．001）。搏动指数低于正常组（P＜0．05）。阻力指数与正常组无显著差异。结果表明，CDFI可作为调查亚临床甲状腺功能低下的敏感方法之一。To investigate the clinical value of color Deppler ultrasound technique for the diagnosis of subclinical hypothyroidism,42 OPD cases with subclinical hypothyroidism,confirmed by clinical and laboratory examinations,were examined by color Doppler ultrasound.The ultrasound manifestations were compared with those of 30 normal persons.In the diseased group,thyroid was diffusely enlarged,the blood flow signals were significantly increased similar to the manifes tations of hyperthyroidism.The diameter of superior thyroid artery widened,and the blood flow speeded up.The systolic maximum flow rate,the end-diastolic minimum flow rate and time-average maximum flow rate were all significantly greater than the control.The PI was lower than that of the control.There was no difference between the two groups in RI.
