目的探讨彩色多普勒血流成像在甲状腺自身免疫性疾病中的应用价值。方法超声观测42例甲状腺自身免疫性疾病的患者(其中,Graves’s病19例,其他自身免疫性甲状腺病患者23例)及健康对照组(甲状腺正常者24例)的甲状腺下动脉收缩期血流峰值速度(SPV)和阻力指数(RI)。结果在所有Graves’s病的患者中,PSV的流速均高于65 cm/s,而其他自身免疫性甲状腺病中,SPV均不超过65cm/s。甲状腺自身免疫性疾病的患者甲状腺下动脉SPV较对照组加快(P<0.01),Graves’s病患者的SPV与其他自身免疫性甲状腺病患者的SPV之间的差异有统计学意义(P<0.01)。三组阻力指数差异无统计学意义(P>0.05)。结论彩色多普勒血流动力学显像有助于甲状腺自身免疫性疾病的鉴别诊断。
Objective To investigate the value of color Doppler flow imaging in thyroid autoimmune diseases. Methods The systolic blood flow peak of the thyroid gland in 42 patients with thyroid autoimmune diseases (including 19 Graves’ s disease and 23 patients with other autoimmune thyroid diseases) and healthy control group (24 patients with normal thyroid gland) Speed (SPV) and Resistance Index (RI). Results In all patients with Graves’s disease, the flow rate of PSV was higher than 65 cm / s, while in other autoimmune thyroid diseases, the SPV was no more than 65 cm / s. The SPV in the thyroid autoimmune disease was significantly higher in the hypothyroid artery than in the control group (P <0.01). There was a significant difference (P <0.01) between the SPV in patients with Graves’ disease and the SPV in other autoimmune thyroid diseases. There was no significant difference in resistance index between the three groups (P> 0.05). Conclusion Color Doppler hemodynamic imaging is helpful for the differential diagnosis of thyroid autoimmune diseases.
