彩色多普勒及高频超声对甲状腺结节性质的鉴别诊断

Differential Diagnosis of Thyroid Nodule with Colour Doppler Ultrasound and High Frequency Ultrasound

目的探讨彩色多普勒及高频超声对甲状腺结节良、恶性鉴别的临床价值。方法利用彩色多普勒及高频超声对57例甲状腺占位患者73个结节进行了超声检查,经手术病理证实结节性甲状腺肿5例19个结节;甲状腺瘤30例31个结节;甲状腺癌22例23个结节。其中,良性结节50个;恶性结节23个。结果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,结节内血流不丰富;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。

Objective To explore the clinical value of differential diagnosis of thyroid nodule with colour doppler ultrasound and high frequency Ultrasound. Methods Total 57cases of thyroid lesion with 73 nodules were examined with colour doppler ultrasound and high frequency Ultrasound. 5 cases of nodular goitre with 19 nodules, 30cases of thyroid adenoma with 31 nodules,22cases of thyroid carcinoma with 23nodules were confirmed by pathology, among them 50nodules were benign ,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 form and 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.
