    INPUT: Supine AP portable view of the chest was obtained . Underlying trauma board partially obscures the view . Given this , the visualized lung fields show no evidence of focal consolidation . No large pleural effusion or evidence of pneumothorax is seen . The very superior lung apices may not be fully included on the image . The cardiac and mediastinal silhouettes are stable and unremarkable . No displaced fracture is seen , although again the superior lung apices may be excluded from the image .
    OUTPUT:
    
Superior lung apices may not be fully included on the image . Otherwise , no evidence of acute intrathoracic process .
