Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Frontal and lateral views of the chest . Relatively low lung volumes are seen . There are indistinct pulmonary vascular markings suggestive of a component of interstitial edema . Bibasilar opacities seen suggestive of atelectasis given low lung volumes versus developing infection . Incidental note is made of an azygos lobe and fissure . Cardiomediastinal silhouette is unchanged . Osseous structures are unremarkable .
    OUTPUT:
    
Findings suggestive of mild interstitial edema . Bibasilar opacities potentially due to atelectasis given the low lung volumes although superimposed infection is also possible .
