Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: An endotracheal tube terminates 4 .1 cm above the carina . In enteric tube terminates in the proximal stomach and could be advanced 5 - 6 cm for ideal positioning . The cardiomediastinal silhouette is stable . Low lung volumes . Minimal elevation of the right hemidiaphragm is also stable . The left lung base is not visualized . Increased opacity at the base of the left lung may reflect atelectasis . There is mild vascular congestion with mild pulmonary edema . No pneumothorax .
    OUTPUT:
    
Endotracheal tube 4 .1 cm of the carina . Enteric tube should be advanced 5 - 6 cm for ideal positioning . No pneumothorax . The left lung base is only partially imaged however opacity at the base of the left lung likely reflects atelectasis or aspiration . Mild pulmonary edema .
