彩色多普勒超声对甲状腺结节良恶性的诊断价值

目的：通过回顾性分析甲状腺良恶性结节超声影像的不同特点，探讨甲状腺良恶性结节的彩色多普勒超声鉴别诊断价值。方法：回顾分析2010-03--2012-05因甲状腺结节就诊并行手术治疗的病人200例，共记录结节358个。手术前行甲状腺彩色多普勒超声检查：记录结节的边界，结节内部回声性质，结节中心部钙化情况，结节内部及边缘血流情况等超声特征。结果：术后病理：甲状腺良性结节253个，恶性结节105个。结节边界不清楚或形态不规则，结节内部呈实性低回声，结节中心部伴砂粒体样微钙化，结节内部不规则丰富血流信号等超声特征在恶性结节中较为常见。结论：对于甲状腺结节而言，没有一项超声特征为良性或恶性结节所独有，须综合分析甲状腺结节彩色多普勒超声影像特点，以提高其鉴别良恶性结节的诊断价值。

THE VALUE OF ULTRASONOGRAPHIC FEATURES ON PREDICTION OF MALIGNANT NODULES

Objective：To analysis the ultrasonic characteristic of malignant nodules and evaluate the diagnostic value of doppler ultrasonography on predicting thyroid malignant nodes. Methods：A total of 200 patients with 358 thyroid nodules were dectcted by doppler ultrasonography in our hospital from March 2010 to May 2012 retrospectively. The ultrasonography features such as shape margin, echotexture,ehogenicity,presence and type of calcification,blood flow inside or around nodules were e-valuated before surgery. Results：253 nolules were benign and 105 were malignant. Ill-defined border, solid and hypoechogenicity calcification and blood flow around the node was frequently seen in margilant nolules. Conclusion：A combined using of conventional ultrasonography features can improve the accuracy of differential diagnosis.
