低剂量胸部CT扫描诊断肺癌应用价值分析

Analysis of the Application Value of Low-dose Chest CT Scan in the Diagnosis of Lung Cancer

目的探讨低剂量胸部CT扫描在诊断肺癌中的应用价值。方法将该院2016年1月—2020年1月间收治的110例肺癌患者作为研究对象,分为研究组以及对照组,每组55例。对照组进行DR检查,研究组采取低剂量胸部CT扫描检查,对比两组患者结节检出率以及诊断符合率。结果研究组≤5 mm结节检出率(3.64%)要低于对照组(14.55%),差异有统计学意义(χ^2=3.960,P=0.047);研究组6~10 mm结节检出率(3.64%)要低于对照组(16.36%),差异有统计学意义(χ^2=4.949,P=0.026);研究组11~20 mm结节检出率(5.45%)要低于对照组(20.00%),差异有统计学意义(χ^2=5.238,P=0.022)。研究组≥21 mm结节检出率(21.82%)要低于对照组(40.00%),差异有统计学意义(χ^2=4.257,P=0.039)。研究组诊断符合率(94.55%)要明显高于对照组(81.82%),差异有统计学意义(χ^2=4.274,P=0.039)。结论低剂量胸部CT扫描诊断肺癌具有较高的诊断符合率,对于不同结节具有较高的检出率。

Objective To explore the application value of low-dose chest CT scan in the diagnosis of lung cancer.Methods A total of 110 lung cancer patients admitted to the hospital from January 2016 to January 2020 were taken as the research objects and divided into a study group and a control group,with 55 cases in each group.The control group underwent DR examination,and the study group underwent low-dose chest CT scan to compare the nodule detection rate and diagnosis coincidence rate between the two groups.Results The detection rate of nodules ≤5 mm in the study group(3.64%)was lower than that of the control group(14.55%),the difference was statistically significant(χ^2=3.960,P=0.047);the detection rate of nodules 6-10 mm in the study group(3.64%)was lower than the control group(16.36%),the difference was statistically significant(χ^2=4.949,P=0.026);the detection rate of 11-20 mm nodules in the study group(5.45%)was lower than that of the control group(20.00%),the difference was statistically significant(χ^2=5.238,P=0.022).The detection rate of nodules ≥21 mm in the study group(21.82%)was lower than that in the control group(40.00%),the difference was statistically significant(χ^2=4.257,P=0.039).The diagnostic coincidence rate of the study group(94.55%)was significantly higher than that of the control group(81.82%),the difference was statistically significant(χ^2=4.274,P=0.039).Conclusion Low-dose chest CT scan has a high diagnostic coincidence rate for the diagnosis of lung cancer,and a high detection rate for different nodules,which is worthy of promotion.
