目的：通过对肺内结节的筛查及定期复查达到早期诊断和鉴别诊断的目的。方法应用多层螺旋CT对40岁以上10908例健康人的肺部进行低剂量或常规剂量的检查和筛查。结果341例中发现341个结节，占3.13%，男性266个结节，占3.71%，女性75个结节，占2.01%，143例定期复查后，120例结节无变化，18例结节缩小，5例结节略增大。结论多层螺旋CT在肺内结节的筛查中具有明显的优势，采用低辐射剂量筛查更具有推广性。

Objective To study the value of screening of pulmonary nodules for early diagnosis and differ-ential diagnosis. Methods A total of 10,908 healthy people aged over 40 years old were enrolled to screen lungs by multislice spiral CT with low-dose or conventional dose. Results A total of 341 nodules (3.13%), of which 266 nod-ules in males (3.71%), and 75 nodules in females (2.01%) were observed. After follow-up in 143 cases, 120 cases with no change in nodules, 18 cases with narrowing nodules, and 5 cases with slightly increasing nodules were detected. Conclusion Multislice spiral CT has obvious advantages in screening for lung nodules, especially in low radiation dose.
