摘要
目的探讨采用超声造影联合彩色多普勒超声进行甲状腺癌颈部淋巴结转移诊断的临床价值。方法选取120例甲状腺癌疑似颈部淋巴结转移患者，分别进行彩色多普勒超声检查和超声造影检查，对颈部淋巴结转移进行评估，并同病理诊断结果进行对比分析。结果彩色多普勒超声影像中淋巴结呈现血流丰富、融合、边界模糊、L/S〈2、皮质增厚等征象者颈部淋巴结转移发生率明显高于其他患者，差异有统计学意义（P〈0.05）；恶性淋巴结节边缘型血流分布特征比例明显高于良性结节，前者门血管型血流分布比例明显低于后者，差异有统计学意义（P〈0.05）；超声造影对于甲状腺颈部淋巴结转移的良恶性判断准确率、敏感度及特异度均明显优于彩色多普勒超声，差异有统计学意义（P〈0.05）。结论对于甲状腺癌患者，可通过彩色多普勒超声检查对颈部淋巴结进行初步定位和血流分布评估，并采用超声造影进行进一步准确的良恶性评估，从而取得准确的诊断结果。
Objective To investigate the clinical value of contrast-enhanced uhrasonography and color Doppler ultrasonography in the diagnosis of cervical lymph node metastasis of thyroid carcinoma. Methods A total of 120 patients with suspected cervical lymph node metastases was selected and examined by color Doppler ultrasonography and contrast-enhanced uhrasonography respectively, and their cervical lymph node metastases were evaluated. And the results were compared with pathological diagnosis. Results The incidence of cervical lymph node metastasis was significantly higher in patients with lymph node having rich blood flow, fusion, fuzzy boundary, L/s 〈 2 and thickened cortex according to color Doppler ultrasonography than that in other patients （ P 〈 0. 05 ）, and the ratio of blood flow marginal distribution in malignant lymph nodes was significantly higher than that in benign nodules （P 〈 0.05 ）, and the ratio of portal vein blood flow distribution in the former was significantly lower than that in benign nodules （ P 〈 0.05 ）. The accuracy, sensitivity and specificity of diagnosis of benign and malignant metastasis by contrast-enhanced uhrasonography were superior to those of diagnosis by color Doppler ultrasonography, the differences were significant （P 〈 0. 05）. Conclusions For patients with thyroid cancer, color Doppler ultrasound can be carried out on the initial determination of cervical lymph nodes and blood flow distribution assessment, and contrast-enhanced uhrasonography for further accurate assessment of benign and malignant, in order to obtain accurate diagnostic results.
