Abstract Objective To compare the advantages and disadvantages of low-dose 64-slice spiral CT and target scanning,and traditional DR chest radiography on screening early lung cancer population,and evaluate the application value of low-dose 64-slice spiral CT scanning with target scanning.Methods From January 2015 to March 2016,362 people with high risk of lung cancer were screened after physical examinations in our physical examination department were selected.All participants were provided with traditional chest radiography and low-dose 64-slice spiral CT scanning with target scanning.Two physicians were invited for outcome observation and diagnosis in double-blind.The results by the two inspection Methods were recorded and comparatively analyzed.Results In traditional DR chest radiography.25 people in high risk of lung cancer group were detected with pulmonary nodules,and the detection rate was 6.91%.In CT,58 participants were detected accounting for 16.02%.The detection rate in CT group was much higher than that in the traditional DR chest radiography (P<0.05).In traditional DR chest radiography,2 people were finally diagnosed as lung cancer,and the detection rate was 0.55%,while in CT scanning with target scanning,9 ones were detected with lung cancer accounting for 2.49%.The detection rate in the latter was higher (P<0.05).Conclusion The detection rate of early lung cancer by 64-slice spiral CT in a low-dose scanning and target scanning is remarkably higher than that by traditional DR chest radiography.Therefore,clinical physicians should attach great importance to 64-slice spiral CT in a low-dose scanning and target scanning,not only focus on the examination results by traditional DR chest radiography.
