    INPUT: The lungs are hyperinflated with emphysematous changes most pronounced in the lung apices . The heart size is normal . Mediastinal and hilar contours are unchanged . The pulmonary vascularity is normal . Previously noted nodules distributed in both lungs are better assessed on the prior CT . No new focal consolidation , pleural effusion or pneumothorax is identified . No displaced fractures are seen . Curvilinear lucency within the left upper quadrant of the abdomen is compatible with gas within a colonic loop of bowel , and is not extraluminal .
    OUTPUT:
    
1 . No acute traumatic injury identified . No displaced rib fractures are seen , though if there is clinical concern for rib fracture , a dedicated rib series is noted . 2 . Emphysema . Known multiple pulmonary nodules are better assessed on the prior CT .
