Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A nasogastric tube ends in the small bowel . Left lower lung linear opacities are most consistent with atelectasis . There is no new focal opacity , pulmonary edema or pneumothorax . There is no large pleural effusion , however , the technique and low lung volumes make evaluation for a small effusion difficult . The cardiac and mediastinal contours are stable . There is no free air .
    OUTPUT:
    
No large pleural effusion . Left lateral decubitus or standard lateral CXR would be more sensitive for detecting a small pleural effusion . No free air .
