Comparison is made to natural language processing (NLP) of the associated radiologist text reports.Materials and Methods: This IRB-approved single-institution retrospective study uses 6749 two-view chest radiograph exams (2012– 2017, 4436 unique subjects, 54% female, 46% male), same-day associated radiologist text reports, and PFT exams acquired within 180 days. The Image Model (Resnet18 pre-trained with ImageNet CNN) is trained using frontal and lateral radiographs and PFTs with 10% of the subjects for validation and 19% for testing. The NLP Model is trained using radiologist text reports and PFTs. The primary metric of model comparison is the area under the receiver operating characteristic curve (AUC).Results: The Image Model achieves an AUC of 0.814 for prediction of obstructive lung disease (FEV1/FVC < 0.7) from chest radiographs and performs better than the NLP Model (AUC 0.704, p< 0.001) from radiologist text reports where FEV1 = forced expiratory volume in 1 second and FVC = forced vital capacity. The Image Model performs better for prediction of severe or very severe COPD (FEV1 < 0.5) with an AUC of 0.837 versus the NLP model AUC of 0.770 (p< 0.001).Conclusion: A CNN Image Model trained on physiologic lung function data (PFTs) can be applied to chest radiographs for quantitative prediction of obstructive lung disease with good accuracy.Keywords: machine learning, chronic obstructive pulmonary disease, quantitative image analysis, natural language processing |
