What this Trial Is About
Researchers are evaluating the use of chest X-ray (CXR) in a large-scale study to screen for thoracic diseases in adults. This observational study involves participants who come for routine health exams and aims to confirm suspected abnormalities with more precise methods like chest CT scans or clinical follow-up. The goal is to determine how well CXR works in detecting early lung, pleural, and heart problems and to provide evidence for its cost-effectiveness and feasibility in public health screening. Participants will undergo digital chest X-rays during their health examinations. When abnormalities are suspected, these findings will be verified using a gold standard reference such as a chest CT scan or through clinical follow-up procedures. The study gathers data across multiple centers to assess detection rates, diagnostic accuracy, false positives, and reading consistency among centers over an average period of one year. During the study, participants will have their chest X-rays analyzed and may be asked to undergo further scans or follow-ups if needed. Researchers will measure the overall detection rate of thoracic diseases, diagnostic performance metrics, and consistency across different centers. The study tracks participants for about one year to monitor these outcomes and better understand the benefits and limitations of using chest X-rays for disease screening.
