Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Frontal and lateral views of the chest were obtained . There are relatively low lung volumes that accentuate the bronchovascular markings . Given this , there are subtle bibasilar opacities which most likely represent atelectasis . However , early infectious process is not excluded in the appropriate clinical setting . No pleural effusion or pneumothorax is seen . The cardiac silhouette is top normal , likely accentuated by low lung volumes . The mediastinum is also likely accentuated by low lung volumes .
    OUTPUT:
    
Low lung volumes which accentuate the bronchovascular markings in the cardiac silhouette . Mild bibasilar opacities likely represent atelectasis ; however , early infectious process is not excluded in the appropriate clinical setting .
