    INPUT: AP and lateral views of the chest . Lower lung volumes seen on the current exam . Even with this , indistinct pulmonary vascular markings suggest component of pulmonary vascular congestion . Bibasilar opacities may be due to atelectasis given low lung volumes , although infection can not be entirely excluded . Cardiomediastinal silhouette is within normal limits for technique . No acute osseous abnormalities identified . Anterior wedging of the T12 vertebral body is unchanged from prior . Air-fluid levels identified in the abdomen , better characterized by CT of the abdomen performed the same day .
    OUTPUT:
