Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Patient is rotated and supine , preventing strict comparison to prior studies . Opacification of the left lung base appears similar compared to multiple prior examinations and likely reflects a combination of moderate pleural effusion and associated atelectasis , but perhaps new consolidation and / or increase in left pleural effusion . Linear opacity in the right lung base is suggestive of subsegmental atelectasis . Prominent interstitial markings are likely secondary to AP supine technique and bronchovascular crowding due to low lung volumes . No overt pulmonary edema is identified . Mediastinal and hilar contours appear within normal limits . Evaluation of the cardiac silhouette is limited due to basilar opacities . No pneumothorax is evident .
    OUTPUT:
    
1 . Persistent left basilar atelectasis and pleural effusion , new pneumonia and / or increase in pleural effusion may well be present . Conventional radiographs recommended , when feasible . 2 . Probable subsegmental atelectasis in the right lung base . 3 . No overt pulmonary edema . chronic elevation left hemidiaphragm increased left opacity - position or new stuff consider PA / lateral
