Abstract:
Objective To study prevalence and clinical significance of coronary artery and aortic calcification in lung cancer screening using spiral CT. Methods 1877 subjects without symptom underwent lung cancer screening using spiral CT. Standard mediastinal windows were used for showing the presence or absence of calcification in coronary arteries and aorta.Results (1)The frequency of coronary artery calcification(CAC) was 15% in total 1877 subjects, the prevalence was higher in male than in famale(P0.05), the prevalence of aortic calcification increased with age in both male and famale. The frequency of calcification was the highest in the arch and lowest in the ascending aorta.Conclusion The lung cancer screening using spiral CT can be used to screen of coronary artery and aortic calcification.The detection of calcification of coronary arteries and aorta has important clinical significance which relates with coronary heart disease.
