摘要
目的探讨彩色多普勒超声对甲状腺癌淋巴结转移的诊断价值。方法将82例甲状腺癌患者按手术病理结果显示是否发生淋巴结转移分为转移组(n=41)和未转移组(n=41)。记录并比较两组患者彩色多普勒超声图像特征、血流分布情况及血流参数,计算彩色多普勒超声诊断甲状腺癌淋巴结转移的特异度和灵敏度。结果彩色多普勒超声诊断甲状腺癌淋巴结转移的灵敏度为82.93%(34/41),特异度为95.12%(39/41)。转移组淋巴结融合、边界不清、皮质增厚、淋巴结偏移、纵横比﹤2的比例均明显大于非转移组,差异均有统计学意义(P﹤0.01)。非转移组患者血流分布情况明显优于转移组,差异有统计学意义(P﹤0.05)。转移组患者搏动指数(PI)、收缩期峰值流速(PSV)均明显高于非转移组,差异均有统计学意义(P﹤0.01)。结论对甲状腺癌患者给予彩色多普勒超声检查可较准确诊断淋巴结转移,非转移和转移淋巴结在淋巴结偏移、纵横比、皮质厚度、是否融合、边界清晰度等征象方面差异较大,结合患者的血流分布进行综合分析,诊断甲状腺癌淋巴结转移的效能较高,值得推广应用。
Objective To explore the diagnostic value of color Doppler ultrasonography in lymph node metastasis of thyroid cancer.Method A total of 82 patients with thyroid cancer were divided into metastasis group(n=41)and nonmetastasis group(n=41)according to presence of lymph node metastasis confirmed by surgery pathology.The imaging characteristics of color Doppler ultrasonography,blood flow distribution,blood flow parameters were recorded and the specificity and sensitivity of color Doppler ultrasonography in diagnosing lymph node metastasis of thyroid cancer were evaluated.Result The sensitivity of color Doppler ultrasonography in the diagnosis of lymph node metastasis of thyroid cancer was 82.93%(34/41),and the specificity was 95.12%(39/41).The proportion of patients with lymph node fusion,unclear boundary,cortical thickening,lymph node migration,and aspect ratio<2 in the metastasis group were higher than those in the non-metastasis group(P<0.01).The blood flow distribution in the non-metastasis group was superior to that in the metastasis group(P<0.05).The pulsatility index(PI)and peak systolic velocity(PSV)of metastasis group were significantly higher than those of non-metastasis group(P<0.01).Conclusion Color Doppler ultrasonography can accurately diagnose lymph node metastasis in patients with thyroid cancer,there are significant difference for the lymph node migration,aspect ratio,cortical thickness,lymph node fusion and boundary definition in non-metastatic and metastatic lymph node.The diagnostic efficacy of lymph node metastasis in thyroid cancer was higher combined with comprehensive analysis of blood flow distribution,which is worthy of application.
