彩色多普勒超声在诊断弥漫性甲状腺疾病中的应用

Application of Color Doppler Ultrasonography in Diagnosis of Diffuse Thyroid Disease

目的 探讨彩色多普勒超声 (CDUS)在诊断弥漫性甲状腺疾病中的价值。方法 对临床确诊的原发性甲状腺机能亢进 (甲亢 )、亚急性甲状腺炎 (亚甲炎 )和亚临床型甲状腺功能低下 (亚甲低 )患者各 2 0例及 2 0例正常人行甲状腺CDUS检查 ,观察甲状腺的二维图像特点及彩色血流灌注情况 ,并测量甲状腺上动脉 (STA)的各血流参数 ,对比分析各组间的上述各指标。结果 三实验组均表现为甲状腺肿大 ,其中亚甲炎组呈弥漫性或局限性低回声 ,前表面不清与颈前肌广泛粘连 ,CDUS示甲状腺血供较丰富 ,STA频谱正常或流速增大。甲亢与亚甲低组二维图像无特异性 ,但甲亢者STA流速增大 ,而亚甲低组流速较低。结论 CDUS对亚甲炎。

Objective To explore the value of color Doppler ultrasonography in diagnosis of diffuse thyroid disease.Methods Three groupe patients consisted of 20 Grave's disease (groupe Ⅰ),20 sub-acute thyroiditis(groupe Ⅱ) and 20 subclinical hypothyroidism (groupe Ⅲ),all confirmed clinically,and 20 normal persons were undergone color Doppler ultrasonography.We observed the ultrasonogram and flow perfusion of the thyroid and measured the hemodynamic parameters of the superior thyroid artery(STA).The results of the three groupe patients were compared.Results A enlarged thyroid was found in all of the 3 groupe patients.In these patients of groupe Ⅱ,diffuse or focus hypoechoic lesion was detected,the anterior face of the thyroid was uncleare,and the color flow signals were abundent in thyroid while the velocity of the STA was normal or increased sligthly. Patients of groupe Ⅰ and Ⅲ had the similar shows on the ultrasonogram,but the velocity of the STA was higher in the former than in the later.Conclusions CDUS was to some extent valuable in differential diagnosis of the diffuse thyroid disease.
