Analysis of Lung Nodules and Lung Cancer Detection by Low-Dose Spiral CT of The Chest During Health Check-Up

Abstract

Objective: To analyze the detection of lung nodules and lung cancer by low-dose spiral computed tomography (CT) of the chest in the population during health checkups. Methods: A total of 1,000 cases were selected for the data study and the data were retrospectively analyzed to detect lung nodules. They were divided into groups according to age, gender, and size of nodules, and the detection of lung nodules and lung cancer was compared. Results: A total of 268 lung nodules were detected, and the detection rates between genders were not significant (P > 0.05). The detection rate of lung nodules increased with age and stabilized after 60 years. When analyzing the size of lung nodules, there were 65 cases of nodules over 8mm. The patients were followed up for 18 months, with 36 cases of visits indicating lung cancer. A total of 10 cases were detected, including 7 cases of adenocarcinoma. Conclusion: Low-dose spiral CT chest examination during checkups can detect lung cancer early so that high-risk lung nodules can be dealt with promptly. Underlying lung adenocarcinoma can also be discovered. Individuals more than 40 years of age should regularly conduct low-dose spiral CT chest examinations to detect the presence of lung nodules or lung cancer as early as possible.
