摘要
目的:探讨低剂量胸部CT扫描诊断肺癌的价值。方法:选择本院2018年1月~2019年6月收治的120例肺癌患者作为观察对象,根据随机数字表随机分为观察组和对照组,每组各60例。对照组采用常规剂量(200mA)CT扫描检查,观察组采用低剂量(40mA)CT扫描检查。结果:对胸部结节进行低剂量CT扫描后检出率与常规剂量CT扫描并无统计学差异(P>0.05);低剂量CT扫描的诊断灵敏度、特异度、阳性预测值以及阴性预测值与常规CT扫描对比差异无统计学意义(P>0.05);低剂量CT扫描与常规剂量CT扫描在肺癌检出率方面差异无统计学意义(P>0.05)。结论:低剂量胸部CT扫描诊断肺癌和常规剂量检出率相当,对检查的患者辐射更小。
Objective:To explore the value of low-dose chest CT scan in the diagnosis of lung cancer.Methods:120 cases of lung cancer patients admitted in our hospital from January 2018 to June 2019 were selected as observation objects,and randomly divided into an observation group and a control group according to a random number table,with 60 cases in each group.The control group was examined by conventional dose(200mA)CT scan,and the observation group was examined by low dose(40mA)CT scan.Results:The detection rate of chest nodules after low-dose CT scan was not statistically different from that of conventional-dose CT scan(P>0.05);the diagnostic sensitivity,specificity,positive predictive value and negative predictive value of low-dose CT scans were not significantly different from those of conventional CT scans(P>0.05);there was no statistically significant difference between low-dose CT scans and conventional-dose CT scans in the detection rate of lung cancer(P>0.05).Conclusion:The detection rate of low-dose chest CT scan for lung cancer is comparable to that of conventional dose,and the radiation to the patients examined is smaller,which is worthy of clinical promotion.
