Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There are low lung volumes , which accentuate the bronchovascular markings . Bibasilar opacities are seen , which could be due to atelectasis and aspiration , although infectious process is not excluded . No large pleural effusions are seen , although a trace pleural effusion is difficult to exclude . There is lucency under the left hemidiaphragm , difficult to discern whether intraluminal or extraluminal / free air . There may have been a similar lucency under the left hemidiaphragm on chest radiograph from ___ , although this is difficult to accurately compare . Findings can be further evaluated on lateral decubitus view or CT to further evaluate concern for pneumoperitoneum .
    OUTPUT:
