摘　　要：目的 探讨彩色多普勒超声血流参数联合MRI评估甲状腺癌患者颈淋巴转移的价值。方法 随机抽选256例于2019年1月至2021年1月我院收治的甲状腺癌患者,分析其彩色多普勒超声血流参数及MRI图像。比较彩色多普勒超声血流参数、MRI检查结果 与病理学检查结果 的一致性;对患者进行病理检查,并以此作为金标准,比较血流参数、MRI检查及联合检查对甲状腺癌颈淋巴转移的诊断效能及诊断价值。结果 经病理学检查得,易出现颈淋巴结转移者95例,未出现颈淋巴结转移者161例;彩色多普勒超声血流参数检查结果 与病理学检查结果 的一致性(Kappa=0.791)高于MRI(Kappa=0.638);通过彩色多普勒超声血流参数对甲状腺癌颈淋巴结转移诊断,发现其灵敏度、准确率高于MRI(P<0.05),两种检查方法 诊断甲状腺癌颈淋巴转移的特异度对比无明显差异(P>0.05);联合检查诊断甲状腺癌颈淋巴转移的AUC为0.904,大于彩色多普勒超声血流参数、MRI检查的0.830、0.804 (P<0.05)。结论 彩色多普勒超声血流参数在诊断甲状腺颈淋巴结转移方面具有较高的灵敏度及准确率,且其联合MRI诊断具有较高的诊断价值。Objective To evaluate the value of color Doppler ultrasonography combined with MRI in evaluating ce rvical lymphatic metastasis in patients with thyroid cancer.Methods 256 patients with thyroid cancer admitted to our hospital from January 2019 to January 2021 were randomly selected to analyze the color Doppler ultrasound blood flow parameters and MRI images.The consistency of color Doppler flow parameters,MRI results and pathological results was compared.The pathological examination of patients was used as the gold standard to compare the diagnostic efficacy and value of blood flow parameters,MRI examination and combined examination for cervical lymph node metastasis of thyroid cancer. Results Pathological examination showed that 95 cases were prone to cervical lymph node metastasis,161 cases did not.The consistency between color Doppler ultrasonography and pathology was higher(Kappa=0.791) than that of MRI(Kappa=0.638).The sensitivity and accuracy of color Doppler ultrasonography were higher than MRI in the diagnosis of cervical lymph node metastasis of thyroid cancer(P<0.05),and there was no significa nt difference in the specificity between the two methods in the diagnosis of cervical lymph node metastasis of thyroid cancer(P>0.05).The AUC of combined examination in diagnosing ce rvical lymphatic metastasis of thyroid cancer was 0.904,which was higher than that of color Doppler ultrasonography and MRI(0.830 and 0.804,P<0.05).Conclusion Color Doppler ultrasonogra phy has high sensitivity and accuracy in the diagnosis of thyroid cervical lymph node metastasis,and its combined diagnosis with MRI has high diagnostic value.
