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 investigate the value of high-frequency ultrasound in the diagnosis of nodular goiter. Methods Totally 89 cases of nodular goiter were diagnosed and diagnosed by high frequency ultrasound. All patients were confirmed by operation and pathology. Results thyroid was irregular, asymmetric swelling, uneven outline, the internal structure of the thyroid uneven, was scattered nodular echo. Nodules to multiple-based, nodular edge is not clear, no capsule, silent halo, nodules were heterogeneous in the middle and low echo. Nodules around the coarse, tortuous bypass blood flow signal, the internal blood flow was not significantly specific. Conclusion High-frequency ultrasound is an important method to diagnose nodular goiter because of its high resolution and sensitivity to the thyroid.
