Cardiomediastinal silhouette is stable given lower inspiratory effort . Osseous and soft tissue structures are unremarkable .
    OUTPUT:
    
Lower lung volumes limiting exam . Bibasilar opacities , potentially due to atelectasis ; however , component of infection is not completely excluded . Clinical correlation suggested and repeat exam with better inspiratory effort can be performed if desired .
