摘要
目的 了解CT、核磁共振(MRI)在诊断甲状腺癌转移淋巴结患者中的价值与敏感性.方法 将病例纳入研究时段定为2021年5月-2022年5月,选择本院在该时间段内收治的150例甲状腺癌患者为探究主体,全部患者均实施CT、MRI检查、联合检查,以手术结果作为诊断金标准,了解淋巴结转移情况,同时分析CT、MRI诊断情况及诊断价值.结果 150例患者术后病理结果显示,有84例发生淋巴结转移,转移率是56.00％,共有淋巴结458个,转移淋巴结有328个;CT发现淋巴结转移患者短长经比值、淋巴结大小、数目均较无转移者高,差异具有价值(P＜0.05);MRI发现淋巴结转移者强化扫描高信号、囊性变、浆膜浸润检出比例较无转移者高,差异具有价值(P＜0.05);CT敏感度为90.24％,特异度为83.08％,准确性为88.21％,MRI分别是92.07％、86.15％、90.39％,联合诊断分别是97.56％、95.38％、96.94％,联合诊断敏感度、特异度、准确性均较CT、MRI高,差异具有价值(P＜0.05).结论 在甲状腺癌转移淋巴结临床诊断中,CT、RI均有较高的诊断价值,与病理检查一致性较高,且二者联合后的诊断价值更高,能够为临床诊断提供客观依据.
Abstract
Objective To investigate the value and sensitivity of CT and MRI in the diagnosis of metastatic lymph nodes of thyroid cancer.Methods The inclusion period of cases was set as May 2021 to May 2022.150 patients with thyroid cancer admitted to our hospital during this period were selected as subjects of study.CT,MRI and combined examination were performed on all patients,and surgical results were taken as the diagnostic gold standard to understand the lymph node metastases and analyze the diagnostic status and value of CT and MRI.Results The postoperative pathological results of 150 patients showed that 84 patients had lymph node metastasis,the metastasis rate was 56.00％,a total of 458 lymph nodes,328 metastatic lymph nodes.CT showed that patients with lymph node metastasis had higher short-length meridian ratio,lymph node size and number than those without lymph node metastasis(P＜0.05).MRI showed that the patients with lymph node metastasis had higher percentage of high signal,cystic change and serosal infiltration than those without lymph node metastasis,and the difference was significant(P＜0.05).The sensitivity,specificity,and accuracy of CT were 90.24％,83.08％,and 88.21％,respectively,for MRI were 92.07％,86.15％,and 90.39％,respectively,and for combined diagnosis were 97.56％,95.38％,and 96.94％,respectively.The sensitivity,specificity,and accuracy of combined diagnosis were higher than those of CT and MRI.The difference was significant(P＜0.05).Conclusion In the clinical diagnosis of metastatic lymph nodes of thyroid cancer,both CT and RI have high diagnostic value,which is consistent with the pathological examination.Moreover,the combination of the two has higher diagnostic value,which can provide objective basis for clinical diagnosis.
