Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The inspiratory lung volumes are decreased from the most recent prior study . There is increased streaky opacification of the right lung base and blunting of the right costophrenic angle reflecting a combination of small pleural effusion and increased atelectasis . Retrocardiac opacification obscuring the left hemidiaphragm is unchanged compatible with small pleural effusion and underlying atelectasis or consolidation . Mild pulmonary vascular congestion and edema is slightly improved from the most recent prior study . No pneumothorax is detected . The cardiac silhouette is mildly enlarged but stable . The mediastinal contours are prominent but unchanged with tortuosity of the thoracic aorta and calcification of the aortic knob . The trachea is deviated to the right by the aortic knob .
    OUTPUT:
    
1 . Slightly improved interstitial edema from ___ . 2 . Unchanged retrocardiac opacification reflecting small left pleural effusion and underlying atelectasis or consolidation . 3 . Increased right basilar atelectasis and unchanged small right pleural effusion .
