Artificial Intelligence (AI) Detection of Incidental Interstitial Opacity on Chest Radiography

The goal of this observational study is to learn how well an artificial intelligence (AI)-based chest X-ray analysis software can incidentally detect interstitial lung disease (ILD), which appears as interstitial opacity, on chest X-rays taken for other reasons, and whether these AI-flagged findings represent true interstitial opacity. The main question it aims to answer is: How often does an AI-flagged interstitial opacity correspond to true ILD? This retrospective study uses existing records: researchers review each participant's follow-up computed tomography(CT), CT report, and final diagnosis to confirm true ILD and reticular opacity.
