目的探讨PET-CT显像判断肺癌转移的临床价值。方法回顾性分析124例肺癌患者治疗前PET-CT显像结果,并与常规CT扫描结果、病理结果对比。结果PET-CT判断肺癌转移的准确率、灵敏度、特异性、阳性预测值、阴性预测值分别为95.2%、96.7%、94.9%、98.3%、94.9%,常规CT的准确率为73.6%;两者准确率比较,P<0.01。结论PET-CT显像判断肺癌转移的准确率高,可为临床制定治疗方案提供依据。
Objective To investigate the clinical value of PET-CT in the diagnosis of lung cancer metastasis. Methods The results of PET-CT imaging before treatment in 124 patients with lung cancer were analyzed retrospectively. The results were compared with the results of routine CT scan and pathology. Results The accuracy, sensitivity, specificity, positive predictive value and negative predictive value of PET-CT were 95.2%, 96.7%, 94.9%, 98.3% and 94.9% respectively. The accuracy of conventional CT was 73.6% The accuracy rate, P <0.01. Conclusion PET-CT imaging to determine the accuracy of lung cancer metastasis can provide the basis for clinical treatment plan.
