Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lung volumes are very low . Within that limitation , the cardiac , mediastinal and hilar contours are probably unchanged . There is apparent asymmetric opacification of the right lung , particularly in the right lower lung , but somewhat hazy lung fields bilaterally , with increased density at the right lung base , although the study is very limited . There is no pleural effusion or pneumothorax .
    OUTPUT:
    
No convincing evidence for pneumonia or aspiration on very limited study . Hazy opacities and patchy opacities at the lung bases may be due to mild vascular congestion and minor atelectasis . Short - term follow - up radiographs are suggested with better inspiration , if feasible , in the event that respiratory symptoms were to persist .
