螺旋CT及PET-CT扫描诊断肺癌的临床价值对比观察

Clinical Value of Spiral CT and PET-CT in the Diagnosis of Lung Cancer

目的探讨螺旋CT与PET-CT扫描对肺癌患者的诊断价值。方法回顾性分析2016年4月—2017年11月在开封市肿瘤医院治疗的70例肺部病变患者的临床资料,均已经病理学诊断,所有患者均于入院14 d内接受螺旋CT、PET-CT影像学检查,比较两种检查方式的诊断结果以及诊断效能。结果 PET-CT的恶性肿瘤检出率为87.14%,明显高于螺旋CT的62.86%,差异有统计学意义(P<0.05);PET-CT的诊断敏感度以及准确度均高于螺旋CT,差异有统计学意义(P<0.05)。结论与螺旋CT相较而言,PET-CT在诊断肺癌方面更具优势,其敏感度及准确度均较高,可为临床治疗提供影像学依据。

Objective To evaluate the diagnostic value of spiral CT and PET-CT scan in patients with lung cancer. Methods The clinical data of 70 patients with pulmonary diseases treated in the hospital from April,2016 to November,2017 were retrospectively analyzed. All the patients were diagnosed pathologically. All the patients were examined by spiral CT and PET -CT within 14 days after admission. The diagnostic results and diagnostic efficacy of the two methods were compared. Results The detection rate of malignant tumor in PET-CT was 87.14%,which was significantly higher than that in spiral CT 62.86%. The difference was statistically significant(P<0. 05). The diagnostic sensitivity and accuracy of PET-CT were significantly higher than those of spiral CT(P< 0.05). Conclusion Compared with spiral CT,PET-CT has more advantages in the diagnosis of lung cancer,and its sensitivity and accuracy are higher,which can provide imaging evidence for clinical treatment.
