    INPUT: Frontal and lateral chest radiographs demonstrate low lung volumes , with increased prominence of the cardiac silhouette and bronchovascular crowding , specifically in both lower lobes . No definite consolidation identified . There is no pleural effusion or pneumothorax . The visualized upper abdomen is unremarkable . Visualized bones are unremarkable .
    OUTPUT:
    
The lung volumes are low with resultant exaggeration of bronchovascular markings in both lower lobes . Linear left retrocardiac opacities likely represent exaggerated vascular markings related to low lung volumes or linear atelectasis than consolidation . No pleural effusion present .
