Abstract

CLINICAL/METHODICAL ISSUE\nArtificial intelligence (AI) has the potential to improve diagnostic accuracy and management in patients with lung disease through automated detection, quantification, classification, and prediction of disease progression.\n\n\nSTANDARD RADIOLOGICAL METHODS\nOwing to unspecific symptoms, few well-defined CT disease patterns, and varying prognosis, interstitial lungs disease represents a\xa0focus of AI-based research.\n\n\nMETHODICAL INNOVATIONS\nSupervised and unsupervised machine learning can identify CT disease patterns using features which may allow the analysis of associations with specific diseases and outcomes.\n\n\nPERFORMANCE\nMachine learning on the one hand improves computer-aided detection of pulmonary nodules. On the other hand it enables further characterization of pulmonary nodules, which may improve resource effectiveness regarding lung cancer screening programs.\n\n\nACHIEVEMENTS\nThere are several challenges regarding AI-based CT data analysis. Besides the need for powerful algorithms, expert annotations and extensive training data sets that reflect physiologic and pathologic variability are required for effective machine learning. Comparability and reproducibility of AI research deserve consideration due to a\xa0lack of standardization in this emerging field.\n\n\nPRACTICAL RECOMMENDATIONS\nThis review article presents the state of the art and the challenges concerning AI in lung imaging with special consideration of interstitial lung disease, and detection and consideration of pulmonary nodules.
