目的探讨超声与CT在甲状 腺癌颈淋巴结转移中的应用价值。方 法 回顾性分析2015年10月-2017年10 月于我院接受手术治疗的92例甲状腺 癌患者的临床资料。所有患者于术前 行超声、CT检查，并于术后接受病理 检查。以病理检查结果为“金标准” 评价超声与CT对甲状腺癌颈淋巴结转 移的诊断准确性，分析超声与CT检查 甲状腺癌颈淋巴结转移的图像特点。 结果 术后病理检查结果显示：92例 甲状腺癌患者发生颈部淋巴结转移41 例(44.57%)；超声诊断甲状腺癌颈淋 巴结转移的灵敏度为80.49%(33/41)， 特异度为86.27%(44/51)，准确率为 83.70%(77/92)；CT诊断甲状腺癌颈淋 巴结转移的灵敏度为73.17%(30/41)， 特异度为76.47%(39/51)，准确率为 75.00%(69/92)。结论 超声与CT对甲 状腺癌颈淋巴结转移的诊断准确性均较 高。

Objective To explore the application values of ultrasound and CT in cervical lymph node metastasis of thyroid cancer. Methods The clinical data of 92 cases of patients with thyroid cancer treated with surgery in our hospital from October 2015 to October 2017 were retrospectively analyzed. All patients were given ultrasound and CT examinations before operation, and given pathological examination after operation. The diagnostic accuracies of ultrasound and CT in the detection of cervical lymph node metastases of thyroid cancer were evaluated by taking the results of pathological examination as the "gold standard", and the images features of ultrasound and CT were analyzed in the detection of cervical lymph node metastases of thyroid cancer. Results Postoperative pathological examination showed that 41 cases (44.57%) were with cervical lymph node metastasis among 92 cases of patients with thyroid cancer. The sensitivity, specificity and accuracy rate were 80.49% (33/41), 86.27% (44/51) and 83.70% (77/92) of ultrasound and were 73.17% (30/41), 76.47% (39/51) and 75.00% (69/92) of CT in the diagnosis of cervical lymph node metastasis of thyroid cancer. Conclusion Ultrasound and CT both have high diagnostic accuracy for cervical lymph node metastases of thyroid cancer.
