健康体检人群中18106例肺部CT检查结果分析

Analysis of 18,106 low-dose spiral CT results in health examination

目的探讨肺部低剂量螺旋CT检查在健康体检中的合理应用。方法分析体检中心2013年全年体检资料中18106例肺部CT检查结果 ,按照年龄、性别进行分组,分别记录正常、陈旧性病变及阳性发现例数,计算阳性检出率并进行统计学分析。结果总阳性检出率为23.46%,男性组与女性组的阳性检出率差异具有统计学意义(P<0.05),随着年龄增长,阳性检出率呈逐渐上升的趋势,40岁以上受检者的总阳性检出率27.44%明显高于40岁以下者9.77%(P<0.05)。结论在健康体检中应建议40岁以上的受检者进行肺部低剂量螺旋CT检查以达到早期发现病变的目的。

Objective To investigate the rational application of chest low-dose spiral CT in health examination. Methods A total of 18,106 cases of CT results in the health examination data in 2013 were grouped by gender and age. The results of normal, old changes and positive detection were recorded respectively and the positive detection rate was calculated and analyzed. Results The total positive detection rate was 23.46%. The positive detection rate between males and females was different and strongly related to age, and the difference had statistical significance （P〈0.05）. The positive detection rate increased with age growing, and that of the group above 40-year-old （27.44%） was much higher than that of the group below the age of 40 （9.77%） （P〈0.05）. Conclusion The chest low-dose spiral CT should be suggested for the participants above the age of 40 in health examination in order to detect the lesion early.
