This category of the thoracic radiology question bank is designed for physicians who wish to reinforce, update, and systematically assess their knowledge of chest imaging. The content comprehensively addresses the radiological interpretation of the lung parenchyma, mediastinum, pleura, chest wall, and vascular structures, using radiography, computed tomography, and advanced clinical correlation. The questions are developed with a diagnostic reasoning approach, simulating real-life clinical practice scenarios, where the correct identification of radiological patterns, classic semiological signs, and differential findings are evaluated. Common and clinically significant pathologies are included, such as pneumonia, tuberculosis, interstitial lung disease, COPD, pleural effusion, pneumothorax, pulmonary thromboembolism, and pulmonary nodules. This question bank not only strengthens visual memory and systematic image analysis but also promotes image-based clinical decision-making. The content is kept up-to-date according to international guidelines and current standards in diagnostic imaging, making it an ideal tool for general practitioners, residents, and specialists seeking to strengthen their thoracic radiology skills.
