Lung mask creation lacks well-defined criteria and standardized guidelines,
leading to a high degree of subjectivity between annotators. In this study, we
assess the underestimation of lung regions on chest X-ray segmentation masks
created according to the current state-of-the-art method, by comparison with
total lung volume evaluated on computed tomography (CT). We show, that lung
X-ray masks created by following the contours of the heart, mediastinum, and
diaphragm significantly underestimate lung regions and exclude substantial
portions of the lungs from further assessment, which may result in numerous
clinical errors.
