    INPUT: Low inspiratory volumes . Allowing for this , the heart is not enlarged . Mild prominence of the mediastinum could reflect low inspiratory volumes . There is some patchy opacity at both lung bases . While this could reflect atelectasis , the appearance is more suggestive of pneumonic infiltrates or areas of aspiration . No CHF , effusion , or pneumothorax is detected . No free air identified beneath the diaphragms .
    OUTPUT:
    
Patchy opacities at both lung bases . Question early pneumonic infiltrate or areas of aspiration . Recommend follow - up chest radiograph after resolution of acute process to confirm resolution . No free air seen beneath the diaphragm .
