摘　　要：目的探讨低剂量CT在健康体检肺结节病筛查中的临床应用。方法选择2013年6月-2015年6月新疆医科大学第一附属医院健康体检人群700例,根据随机原则分为实行常规CT检测的人群(对照组)和实行低剂量CT检测的人群(实验组),每组350例。比较2组人群肺结节的检出率、患者辐射剂量、图像质量及检测费用。结果实验组与对照组肺结节病检出率以及图像质量比较差异无统计学意义(P>0.05)。实验组的辐射剂量中有效管球剂量、剂量的长度乘积、放射的容积剂量以及总管球剂量均小于对照组,差异有统计学意义(P<0.05)。实验组的检测费用低于对照组,差异有统计学意义(P<0.05)。结论低剂量CT与常规CT检测相比,低剂量CT检测的辐射剂量更少,更适用于健康体检中筛查肺结节病。Objective To investigate the clinical application of low-dose CT in the screening of lung tuberculosis in healthy examination.Methods One hundred and eighty-six healthy individuals from the First Affiliated Hospital of Xinjiang Medical University from June 2013 to June 2015 were divided into control group and routine experimental group,with each group having 350 cases.The detection rate of pulmonary nodules,the dose of radiation,the quality of images and the cost of testing was compared.Results There was no significant difference between the experimental group and the control group（P〈0.05）.The dose of the radiation,the volume of the radiation and the total dose of the ball were less than that in the control group,the difference was statistically significant（P〈0.05）.The detection cost of the experimental group was lower than that of the control group,the difference was statistically significant（P〈0.05）.Conclusion Low dose CT with routine CT detection compared to low dose CT detection of radiation was more suitable for screening in healthy physical examination of pulmonary nodules of the disease.
