Abstract: Objective To investigate the CR low dose radiography to COPD in patients with pseudo normal phenomenon.Methods 160 cases of COPD diagnosed,stratified random dividing method according to the pulmonary function test values were divided into A,B,C and D group.Each group had 32 cases,at the same time,the increase in lung function in patients with mild to moderate pulmonary emphysema in 32 cases was E group,wich was treated with normal dose as a control group,in the normal dose and low dose CR photography failed to clear the diagnosis of emphysema,causing false normalization,statistical the case number,and verify the pulmonary function classification criteria,identify false normalization of lesions in such a case,the general rule to judge the feasibility analysis and prevention.Results There was no significant chifference among 5 groups of pseudo normal comparison (x2 =4.56,P ＞0.05).Conclusion Chronic obstructive pulmonary disease with low dose CR photography on severe and extremely severe patients is deteded by emphysema detection with rate high.Moderate,mild COPD detection rate is extremely low.
