目的 研究断层扫描(CT)与彩色 多普勒超声联合诊断甲状腺癌的应用价 值。方法 回顾性分析收集我院自2014年1 月至2015年9月收治的98例疑似甲状腺癌 患者作为研究对象，本组患者均行CT薄 层扫描及颈部彩超检查，以病理诊断结 果为金标准，对比联合CT、彩超与单一诊 断方法的诊断价值。结果 98例疑似甲状 腺癌患者确诊为TC的患者有82例；CT对乳 头状甲状腺癌诊断的准确率显著高于彩超 (χ2 =3.521，P<0.05)。CT对甲状腺癌诊 断的灵敏度，特异性，阳性预测值和阴 性预测值分别为89.2%，27.3%，70.7%和 56.25%；彩超对甲状腺癌诊断的灵敏度， 特异性，阳性预测值和阴性预测值分别为 88.3%，21.2%，54.8%和62.5%；CT联合彩 超对甲状腺癌诊断的灵敏度，特异性， 阳性预测值和阴性预测值分别为96.2%， 68.4%，92.7%和81.25%。结论 对甲状腺 癌患者联合计算机断层扫描(CT)与彩色多 普勒超声(彩超)进行诊断较单一方法更可 靠，具有较好的临床应用价值。

Objective To study the clinical application value of computed tomography (CT) and color doppler ultrasound on the diagnosis of thyroid carcinoma. Methods A retrospective analysis of 98 cases of suspected thyroid cancer patients from September 2015 to January 2014 were collected as the research object, the patients were treated with CT thin layer scanning and color Doppler ultrasound examination, the diagnosis value of combined CT and color Doppler ultrasound and single diagnostic method were evaluated. Results 82 cases of patients were diagnosed as TC. The accurate rate of CT in the diagnosis of papillary thyroid carcinoma was significantly higher than that of color Doppler ultrasound (χ2 =3.521, P<0.05). The sensitivity, specificity, sensitivity, specificity, positive predictive value and negative predictive value of CT on the diagnosis of TC were 89.2%, 27.3%, 70.7% and 56.25%, respectively. The sensitivity, specificity, sensitivity, specificity, positive predictive value and negative predictive value of color Doppler ultrasound on the diagnosis of TC were 88.3%, 21.2%, 54.8% and 62.5%, respectively. The sensitivity, specificity, sensitivity, specificity, positive predictive value and negative predictive value of combined CT and color Doppler ultrasound on the diagnosis of TC were 96.2%, 68.4%, 92.7% and 81.25%, respectively. Conclusion The combined CT and color Doppler ultrasound on the diagnosis of TC was more reliable on the diagnosis of thyroid cancer than that of CT or color Doppler ultrasound, alone. And it has better clinical application value.
