    INPUT: The lungs are hypoinflated . There is mild pulmonary vascular congestion . There is no focal consolidation . There is no pneumothorax or pleural effusion . The mediastinal and cardiac contours appear enlarged from prior , which may be due to patient obliquity , hypoinflation and technique .
    OUTPUT:
    
1 . The mediastinum and cardiac silhouettes appear enlarged compared to prior . This may be due to patient obliquity , hypoinflation and AP technique , however other pathologies can not be excluded based on this imaging alone . 2 . Mild pulmonary vascular congestion .
