彩色多普勒及高频超声在鉴别甲状腺结节中的临床应用价值

目的探讨彩色多普勒及高频超声对甲状腺良、恶性结节鉴别诊断的临床价值。方法利用彩色多普勒及高频超声对60例甲状腺占位患者78个结节进行检查，描述结节大小、形态、边界及内部回声、内部及周围血流信号。结果经手术病理证实，结节性甲状腺肿6例20个结节；甲状腺瘤34例35个结节；甲状腺癌20例23个结节。其中良性结节55个，恶性结节23个。良性甲状腺结节大部分表现为边界清楚、形态规则、内部为高回声，结节内部血流信号不丰富；恶性甲状腺结节大部分表现为边界模糊、形态不规则、内部为不均质低回声、部分出现微粒样钙化，结节内部血流信号丰富。结论彩色多普勒及高频超声对甲状腺结节良恶性的鉴别有明确的临床价值。

Differential diagnosis of thyroid nodule with colour Doppler ultrasound and high frequency ultrasound

Objective To explore the clinical value of differential diagnosis of thyroid nodule with colour Dopper ultrasound and high frequency ultrasound. Methods 60 cases of thyroid lesion with 78 nodules were examined with colour Doppler ultrasound and high frequency ultrasound. 6 cases of nodular goiter with 20 nodules, 34 cases of thyroid adenoma with 35 nodules, 20 cases of thyroid carcinoma with 23 nodules were confirmed by pathology, among them 50 nodules were benign and 23 nodules malignant. Results Benign nodules visualized the character of well-defined margin, regular form, hyperechonic and low blood flow in the inner part of the nodules, whereas malignant nodules had the character of indistant margin, irregular from hypoechonic, microcalcifation, high blood flow in the inner part of the nodules. Conclusion Colour Doppler ultrasound and high frequency ultrasound had clinical value of differential diagnosis on thyroid nodule.
