甲状腺结节性疾病超声诊断的临床意义

目的：回顾性研究超声对鉴别的结节良恶性的价值。方法：对比分析经手术病理证实的649例甲状腺结节中的良性结节与恶性结节的超声声像图特征。结果：甲状腺结节性疾病中良恶性结节的超声征象：纵横比、壁结构、声晕、内部回声、钙化形态等方面差异有统计学意义（P〈0．05），恶性结节内血管分布状况及结节内血流阻力示较良性结节差异亦有统计学意义（P〈0．05）。结论：超声对鉴别甲状腺良恶性结节有重要价值。

The Clinical Significance of Ultrasound in Diagnosing Thyroid Nodular Disease

Objective： To retrospectively summarize the clinical value in differential diagnosis of benign and malignant thyroid nodal by ultrasonography. Method： Reviewed 649 cases of thyroid nodal lesions by ul- trasonic examination, summarized the sonogram echogram characters and compared with the results of surgical operation and pathology. Result： In those thyroid nodal lesions, significant difference （ P〈0.05 ） was in ultrasound two dimensional sonogram signs like anteroposterior to transverse diameter ratio （A/T）, wall structure, internal echoes and shape of calcification and so on. Statistical significance （ P〈0.05 ） was appeared in resistance index and vascular distribution in malignant nodules. Conclusion：Great advantage on differentiation thyroid malignant nodal by uhrasonography.
