Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The endotracheal tube ends 3 .7 cm above the level of the carina . A right pleural catheter ends at the right lung apex , not significantly changed . An enteric catheter courses below the level of the diaphragm with its side port just below the level of the gastroesophageal junction . A severe interstitial abnormality may be minimally improved compared to the prior radiograph from earlier today . Focal lucency at the medial right lung base is slightly less conspicuous on the present study , possibly a small pneumothorax or extrapleural gas collection . Marked subcutaneous air has decreased on the left , but is not significantly changed on the right . The heart size remains normal .
    OUTPUT:
    
1 . Slight decrease in conspicuity of lucency along the medial right lung base , possibly a tiny pneumothorax versus extrapleural gas collection . 2 . Slight improvement in widespread interstitial opacities . 3 . Large quantity of subcutaneous air overlying the chest , decreased on the left , but not significantly changed on the right .
