Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Evaluation is somewhat limited by patient rotation . Endotracheal tube terminates approximately 3 cm from the carina . An enteric tube tip is within the stomach . Cardiac and mediastinal contours appear within normal limits . Lung volumes are low with patchy opacities in the lung bases , potentially atelectasis , but infection or aspiration can not be excluded . There is likely a small right pleural effusion . There is mild upper zone vascular redistribution which may be accentuated by supine technique . No overt pulmonary edema is demonstrated . No large pneumothorax is identified . There are no acute osseous abnormalities detected .
    OUTPUT:
    
1 . Limited exam . 2 . Standard positioning of the endotracheal and enteric tubes . 3 . Patchy opacities in the lung bases may reflect atelectasis but infection and / or aspiration are not excluded . 4 . Small right pleural effusion and mild pulmonary vascular congestion .
