目的：分析彩色多普勒血流成像（CDFI）检查甲状腺时出现“火海征”的相关疾病的声像图特征，并对其进行鉴别诊断。方法回顾分析我院85例CDFI呈“火海征”甲状腺的大小形态、内部回声，观测甲状腺上动脉血流频谱特征、峰值流速及阻力指数（RI）。结果毒性弥漫性甲状腺肿（甲亢）、慢性淋巴细胞性甲状腺炎（桥本甲状腺炎）、亚临床甲状腺功能低下（亚甲低）CDFI均可出现“火海征”，但各自声像图特征及甲状腺上动脉血流频谱、峰值流速及RI存在差异。结论甲状腺CDFI出现“火海征”多见于甲亢，但并不是甲亢所特有，在桥本甲状腺炎及亚甲低等甲状腺疾病中都可出现“火海征”声像图，应结合各自声像图表现及甲状腺上动脉频谱、流速及RI改变加以鉴别。

Objective By color Doppler flow imaging (CDFI), to analyse and check thyroid sonographic fea-tures “flames sea sign” of related diseases for differential diagnosis. Methods Retrospectively analyze thyroid size and shape, internal echo of 85 cases whose CDFI showed “flames sea sign”, observe the spectral characteristics of the thyroid artery arterial blood flow, peak velocity and resistance index(RI). Results CDFI of toxic diffuse goiter (hy-perthyroidism), chronic lymphocytic thyroiditis (Hashimoto′s thyroiditis) and subclinical hypothyroidism (methylene low) might occur “flames sea sign”, but their thyroid sonographic features ,the arterial blood flow, peak velocity and RI spectral had differences. Conclusion Thyroid CDFI with “flames sea sign” is more common in hyperthyroidism, but not unique to hyperthyroidism, and it can occur in Hashimoto′s thyroiditis and methylene inferior thyroid disease. Sonogram should be combined with each sonographic and arterial spectrum and velocity and RI change to identify the thyroid gland.
