Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Single semiupright AP image of the chest . There are low lung volumes with bronchovascular crowding . Prominent interstitial markings are seen , left greater than right , which are increased from prior exam and are consistent with increased moderate pulmonary edema . The previously seen bibasilar opacities have decreased slightly from prior exam . These opacities likely represent atelectasis , but can not exclude pneumonia or aspiration in the right clinical setting . No large pleural effusion or pneumothorax is seen . The cardiomediastinal silhouette is very enlarged , similar to prior exams .
    OUTPUT:
    
1 . Moderate pulmonary edema , increased from prior exam . 2 . Bibasilar opacities , slightly decreased from prior exam and likely representing atelectasis , but can not exclude pneumonia or aspiration in the right clinical setting .
