100例甲状腺癌应用CT联合高频超声诊断的价值观察

Value of CT Combined with High-frequency Ultrasound in the Diagnosis of 100 Cases of Thyroid Cancer

目的观察100例甲状腺癌(TC)应用CT联合高频超声诊断的价值。方法选择我院2017年1月至2018年12月100例TC患者为研究对象,均术前自愿接受CT、高频超声检查,将两种检查方法及联合诊断结果与术后病理结果对照分析。结果CT诊断符合率为75.00%,高频超声诊断符合率为57.00%,CT诊断符合率明显较高,差异有统计学意义(χ2=7.219,P=0.007);CT诊断微小乳头状癌的符合率为25.00%,高频超声诊断符合率为16.67%,二者比较差异无统计学意义(χ2=0.253,P=0.615);联合检查的诊断符合率为88.00%,明显高于CT、高频超声检查,差异有统计学意义(χ2=5.604、24.100,P=0.018、<0.001)。结论CT联合高频超声诊断可明显提高TC诊断准确率,对术前准确判断肿瘤大小、性质、确定具体的手术治疗方案具重要指导意义。

Objective To observe the value of CT combined with high-frequency ultrasound in the diagnosis of 100 cases of thyroid cancer(TC).Methods A total of 100 patients with TC from January 2017 to December 2018 in our hospital were selected for the study.All patients were given CT and high-frequency ultrasound voluntarily before operation.The results of two methods and combined diagnosis were compared and analyzed with postoperative pathological results.Results The coincidence rate of CT diagnosis was 75.00%and the coincidence rate of high-frequency ultrasound diagnosis was 57.00%,and the coincidence rate of CT diagnosis was significantly higher(χ2=7.219,P=0.007).The coincidence rate of CT diagnosis of micropapillary carcinoma was 25.00%and the coincidence rate of high-frequency ultrasound diagnosis was 16.67%(χ2=0.253,P=0.615).The diagnostic coincidence rate of combined examination was 88.00%,which was significantly higher than that of CT or high-frequency ultrasound examination(χ2=5.604,24.100,P=0.018,<0.001).Conclusion CT combined with high-frequency ultrasound diagnosis can significantly improve the accuracy rate of TC diagnosis,and it has important guiding significance for accurately determining the tumor size and nature and determining the specific surgical treatment regimen before operation.
