    INPUT: Compared with the prior film , there is probable increased vascular plethora and increased bibasilar atelectasis . No definite consolidation Increased retrocardiac density is similar to the prior film , allowing for differences in technique , though the superior left heart border is slightly less distinct . Minimal blunting of the right costophrenic angle noted , suggestive of a small effusion . Cardiomediastinal silhouette is unchanged , with cardiomegaly and prominence of the main pulmonary artery and both hila .
    OUTPUT:
    
Suspect some increased vascular congestion . New bibasilar atelectasis . No definite focal infiltrate . If clinically indicated , a lateral view may help to further assess the lung bases for infiltrate .
