- W3030360112 abstract "ObjectiveTo study the application value of chest low-dose spiral CT for the screening of lung cancer in physical examinees.MethodsThe data of physical examinees that underwent chest low-dose CT for screening of lung cancer from January 2013 to January 2016 was analyzed, the index included the correlation between age and sex with the detection rate of lung nodules and the detection rate of lung cancer, pathological types and clinical stages of lung cancer and so on.Results9 762 physical examinees underwent chest low-dose spiral CT, the detection rates of pulmonary nodules and lung cancer were 58.16% (5 678/9 762) and 0.34% (33/9 762) respectively. The detection rate of lung cancer increased with the age, the highest detection rate [1.13% (8/709)] of lung cancer was found in 80 years old and above, the rate in 60-69 years old group was 0.36% (6/1 641). In 33 cases of lung cancer, there were 22 cases in stage Ⅰ, 5 cases in stage Ⅲ, and 6 cases in stage Ⅳ. Early diagnosis rate was 66.67% (22/33). Compared with the conventional thoracic spiral CT, the low-dose chest CT had loner radiation dose (P < 0.05), and the image can meet the diagnostic requirement.ConclusionsChest low-dose spiral CT has great advantages in the detection of pulmonary nodules and early stage lung cancer. The application of low-dose CT in physical examinees, especially in high-risk groups of lung cancer, can improve the positive rate of lung cancer screening.Key words: Lung neoplasms; Tumor screening; Detection rate; Tomography, spiral computed" @default.
