Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Endotracheal tube is seen terminating approximately 2 .7 cm above the level of the carina . Enteric tube seen coursing below the level of the diaphragm , inferior aspect not included on the image , but side port appears to be in the left upper quadrant in expected location of the stomach . There is left base opacity which may represent combination of pleural effusion and atelectasis or underlying consolidation due to aspiration or contusion . Additional left perihilar opacity is seen which may also relate to aspiration , asymmetric pulmonary edema , or infection . There is slight blunting of the right costophrenic angle and a trace pleural effusion may be present . The cardiac and mediastinal silhouettes are grossly stable . The superior mediastinum remains widened although slightly less prominent as compared to this prior study and findings are likely accentuated by supine position in the AP technique . However , if there is clinical concern for acute mediastinal injury , CT is more sensitive .
    OUTPUT:
    
1 . Endotracheal and nasogastric tubes in appropriate position . 2 . Left base opacity may be combination of pleural effusion and atelectasis with also aspiration . Additional opacity in the left lung may be due to additional areas of aspiration , although infection or contusion / pulmonary hemorrhage is not excluded within the appropriate clinical setting . 3 . Possible trace right pleural effusion . 4 . Prominence of the superior mediastinum likely accentuated by supine position and AP technique and appears slightly less prominent as compared to the prior study ; however , if there is concern for acute mediastinal process , chest CT is more sensitive .
