摘　　要：目的探讨CT联合超声对甲状腺癌颈部淋巴结(LN)转移的诊断价值。方法选取2021年1月至2022年12月三原县医院收治的80例甲状腺癌患者作为研究对象,所有患者均同时接受CT和超声检查。统计80例甲状腺癌患者的病理检查结果;以病理检查结果为金标准,比较不同检查方式对中央区、颈侧区LN转移及甲状腺癌TNM分期的诊断阳性率;比较不同检查方式对甲状腺癌颈部LN转移的诊断效能。结果80例甲状腺癌患者经病理检查确诊为颈部LN转移的有58例(中央区转移21例,颈侧区转移37例),无颈部LN转移22例;甲状腺癌TNM分期:T1~T2期48例,T3~T4期32例。CT、CT联合超声检查对中央区、颈侧区LN转移的诊断阳性率高于超声检查(P<0.05)。CT、CT联合超声检查对甲状腺癌T1~T2期和T3~T4期的诊断阳性率高于超声检查(P<0.05)。CT联合超声检查对甲状腺癌LN转移的诊断灵敏度高于CT、超声检查,准确度高于超声检查(P<0.05)。结论CT联合超声检查对甲状腺癌颈部各部位LN转移及TNM分期均有良好的诊断效果,具有较高的甲状腺癌颈部LN转移诊断效能。Objective To explore the diagnostic value of CT combined with ultrasonography in cervical lymph node(LN)metastasis of thyroid cancer.Methods A total of 80 patients with thyroid cancer admitted in Sanyuan County Hospital from January 2021 to December 2022 were selected as the research objects.All patients underwent CT and ultrasonography at the same time.The pathological examination results of 80 patients with thyroid cancer were counted;taking the pathological examination results as the gold standard,the diagnostic positive rates of different examination methods for LN metastasis in the central and lateral cervical regions and TNM staging of thyroid cancer were compared;the diagnostic efficacy of different examination methods for cervical LN metastasis in thyroid cancer were compared.Results Among 80 patients with thyroid cancer,58 cases(21 cases of central LN metastasis,37 cases of lateral LN metastasis)were diagnosed as cervical LN metastasis by pathological examination,and 22 cases had no cervical LN metastasis;thyroid cancer TNM staging:48 cases in T1-T2 stage and 32 cases in T3-T4 stage.The positive rates of CT and CT combined with ultrasonography in the diagnosis of LN metastasis in the central and lateral cervical regions were higher than those of ultrasonography(P<0.05).The positive rates of CT and CT combined with ultrasonography in the diagnosis of T1-T2 stage and T3-T4 stage thyroid cancer were higher than those of ultrasonography(P<0.05).The sensitivity of CT combined with ultrasonography in the diagnosis of LN metastasis of thyroid cancer was higher than that of CT and ultrasonography,and the accuracy was higher than that of ultrasonography(P<0.05).Conclusion CT combined with ultrasonography has a good diagnostic effect on LN metastasis in all parts of cervical regions and TNM staging of thyroid cancer,and has a high diagnostic efficiency for cervical LN metastasis of thyroid cancer.
