摘　　要：目的:评价超声对亚急性甲状腺炎(亚甲炎)的诊断价值。方法:回顾分析了经病理或临床明确诊断为亚甲炎48例患者的声像图特征、彩色多普勒血流显像(CDFI)及实验室检查。结果:43例甲状腺弥漫性肿大,其中39例呈片状低回声,4例甲状腺弥漫性回声减低增粗欠均;5例甲状腺局限性结节样肿大,呈低回声;44例超声诊断为亚甲炎,诊断符合率为91.67%(44/48)。彩色多普勒显示,片状低回声周边血流信号较丰富,内部无血流信号,甲状腺上动脉血流速度趋于正常。甲状腺吸131I率和激素测定有“分离现象”。结论:超声能直观显示病变形态、范围及损伤程度,从而为亚甲炎的诊断、治疗及病情评价提供客观依据。Objective. To evaluate the diagnostic value of ultrasonography in the subacute thyroiditis. Methods. Data of ultrasonographic and CDFI in 48 cases with subacute thyroiditis, to have been demonstrated by the pathology were reviewed. Results： 39 cases of 48cases with the subacute thyroiditis found hypoechogenicity ultrosongrphy; 4 cases asymmetric hypoecho with small focal hyperecho, 5 cases show irregularly and nodal enlargement. The diagnose rate of subacute thyroiditis was 91. 67% （44/48）. CDFI showed that had richer color blood flow signal in the edge and had no color blood flow signal in the interior of the lesions. The velocity of upper artery of thyroid was normal. There was a separate phenomenon between ^131I uptake ratio and thyroid hormone. Conclusions： Ultrasonography can be used as a sensitive index for judgment of damage intensity of thyroid.
