Abstract

Objective: Evaluate the role of low-dose computed tomography (LDCT) in lung nodule screening using the Lung-RADS scoring system. Subjects and Methods: This is a prospective cross-sectional study. Patients underwent LDCT for lung nodule screening at Hanoi Medical University Hospital from January 2024 to December 2024. Results: A total of 3,527 cases underwent LDCT for lung cancer screening. The mean age was 56.5 ± 12.4 years, with 61.5% over 50 years old and 48.5% under 50 years old. The male-to-female ratio was 4:1. Negative screening results (Lung-RADS 1 or Lung-RADS 2) were found in 3,431 cases (97.3%). Positive screening results (Lung-RADS 3 or 4) were found in 96 cases (2.7%), including 82 cases (2.3%) with lung lesions requiring follow-up LDCT in 3–6 months and 14 cases (0.4%) that underwent biopsy and were pathologically diagnosed with lung cancer. All detected lung cancer cases were in the early stage, with tumor sizes <3 cm and no lymph node or distant metastasis.
