Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: An endotracheal tube is 2 cm from the carina . A nasoenteric catheter tip is not fully imaged , though is at least below the diaphragm . Left approach central venous catheter terminates in the mid SVC , unchanged . Complete lobar collapse of the left lower lobe has decreased . However , opacity within the left base persists and is likely a combination of partial left lower lobe collapse and a moderate effusion . A new opacity in the medial right lung base may be due to interval atelectasis or aspiration . The upper lungs are clear . There is no overt edema . No pneumothorax is evident . Cardiomediastinal contours are unchanged .
    OUTPUT:
    
1 . Partial expansion of a previously collapsed left lower lobe , though with persistent partial atelectasis and a moderate left effusion . 2 . New small right basal opacity , possible interval atelectasis or aspiration .
