摘要
目的探讨高频超声在结节性甲状腺肿诊断中的应用价值。方法采用高频超声对89例结节性甲状腺肿进行检查并诊断,全部患者经手术及病理证实。结果甲状腺呈不规则,非对称性肿大,轮廓不平,甲状腺内部结构不均匀,呈散在性结节回声。结节以多发为主,结节边缘欠清晰,无包膜,无声晕,结节内部呈不均质的中低回声。结节周边呈粗大、迂曲的绕行血流信号,内部血流分布无明显特异性。结论高频超声由于其对甲状腺的高分辨率、高敏感性,可于病变早期即可发现异常,不失为诊断结节性甲状腺肿的一项重要的方法。
Objective To evaluate the role of high frequency ultrasound in the diagnosis of nodular goiter. Methods 89 patients with nodular goiter were examined with high frequency ultrasound, all cases were confirmed by surgery and pathological examination. Results High frequency ultrasound can characterize the presence of cystic versus solid elements, the degree of echogenicity of sold elements, the existence of calcifications, and the regularity and definition of the nodule borders. Conclusion High frequency ultrasound is valuable in the diagnosis of nodular goiter.
