二维及彩色多普勒显像对原发性甲状腺功能亢进的诊断意义

Diagnosis of primary hyperthyroidism based on two-dimensional Ultrasound and color Doppler flow imaging

目的探讨二维及彩色多普勒超声对原发性甲状腺功能亢进的诊断意义。方法对48例甲亢患者及30例正常人行超声检查,并结合心率及T3、T4的结果进行对比分析。结果甲亢患者甲状腺三径测值显著增大,与对照组比较,差异有统计学意义(P<0.01),腺体回声增粗,呈非均匀低回声,血流信号增多。心率加快,甲状腺上动脉收缩期峰值流速明显升高,与T3、T4升高呈正相关(r=0.87,P<0.01)。阻力指数明显降低。结论超声在原发性甲亢中有较快、较准确的诊断价值。

Objective To investigate the diagnosis of primary hyperthyroidism based on the two-dimensional ultrasound and color Doppler ultrasound.Methods By analyzing and comparing the results of Ultrasonography between 48 cases and 30 controls,combining with heart rate,T3、T4.Results Compared with controls,the thyroid of patients with hyperthyroidism becomes enlarged in three diameters with significant difference（P0.01）,the echotexture of glands becomes coarse,not even and low,and the blood flow signal was enhanced.The heartbeat rates of patients were accelerated,and the velocity peak of superior thyroid artery in systole period was significantly elevated,and positively correlated（r=0.87,P0.01） with T3、T4.The resistance index was decreased dramatically.Conclusion Ultrasonography is faster and more accurate in the diagnosis of primary hyperthyroidism.
