Current Practices and Future Directions of LD-CT in Lung Cancer Screening.

This article focuses on current practices and future directions of low-dose computed tomography (LD-CT) in lung cancer screening. LD-CT is preferred for screening high-risk adults, particularly those with significant smoking histories, as it detects early lung nodules while minimizing radiation exposure. Screening eligibility criteria and protocols, including the use of the American College of Radiology Lung Screening Reporting and Data System (Lung-RADS), emphasize standardized imaging, structured reporting, and shared decision-making. Emerging tools such as artificial intelligence models like Sybil show promise in improving risk prediction and workflow efficiency. Future efforts aim to enhance equitable access, integrate environmental and hereditary risk factors, and reduce harms such as false positives and patient distress through clear communication and quality assurance.
