    INPUT: PA and lateral views of the chest are compared to previous exam from ___ . Compared to prior , there are significantly lower lung volumes seen . Bibasilar opacities , particularly on the lateral may be therefore secondary to atelectasis ; however , clinical correlation is recommended to exclude infection . Cardiac silhouette also appears more prominent in size , however , also potentially in part due to low lung volumes . Osseous and soft tissue structures are unremarkable .
    OUTPUT:
    
Lower lung volumes on the current exam . Bibasilar opacities , potentially due to atelectasis however , clinical correlation suggested regarding possibility of infection . Apparent increased size of the cardiomediastinal silhouette potentially also due to poor inspiratory effort .
