低剂量胸部CT与DR对肺癌的诊断效能比较

Comparison of diagnostic efficacy of low-dose chest CT and DR for lung cancer

目的比较低剂量胸部计算机断层扫描(CT)与直接数字化X线摄影(DR)对肺癌的诊断效能。方法收集2019年1月至2021年1月进入本院接受诊疗的60例肺癌疑似患者,均接受低剂量胸部CT、DR诊断。以病理结果作为金标准,比较低剂量胸部CT、DR的结节检出结果及其诊断肺癌的效能。结果病理结果显示,60例肺癌疑似患者中,有50例确诊为肺癌。低剂量胸部CT检出48个结节,DR检出37个结节,低剂量胸部CT对最大直径≤5、6~10 mm结节的检出率高于DR,差异具有统计学意义(P<0.05)。低剂量胸部CT诊断肺癌的符合率高于DR,差异具有统计学意义(P<0.05);低剂量胸部CT诊断肺癌的灵敏度高于DR,差异具有统计学意义(P<0.05)。结论与DR技术相比,低剂量胸部CT在肺癌诊断中的应用效果更为显著,可提升结节检出率、诊断效能,为肺癌的临床诊治提供可靠依据。

Objective To compare the diagnostic efficacy of low-dose chest computed tomography(CT)and direct digital radiography(DR)for lung cancer.Methods Sixty patients with suspected lung cancer admitted in our hospital from January2019 to January 2021 were collected and diagnosed with low-dose chest CT and DR.With pathological results as the gold standard,the nodule detection results of low-dose chest CT and DR and their efficacy in the diagnosis of lung cancer were compared.Results The pathological results showed that 50 cases were diagnosed as lung cancer among 60 patients with suspected lung cancer.The low-dose chest CT detected 48 nodules and DR detected 37 nodules.The detection rates of low-dose chest CT for nodules with maximum diameter≤5 and 6-10 mm were higher than those of DR,and the differences were statistically significant(P<0.05).The coincidence rate of low-dose chest CT in the diagnosis of lung cancer was higher than that of DR,and the difference was statistically significant(P<0.05).The sensitivity of low-dose chest CT in the diagnosis of lung cancer was higher than that of DR,and the difference was statistically significant(P<0.05).Conclusion Compared with DR technology,low-dose chest CT is more effective in the diagnosis of lung cancer,which can improve the detection rate of nodule and diagnostic efficiency,and provide a reliable basis for clinical diagnosis and treatment of lung cancer.
