Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The endotracheal tube terminates 4 .5 cm from the carina . Nasogastric tube courses below the diaphragm with the tip in the stomach . However , the side port of nasogastric tube is above the diaphragm . Advancement is recommended . The lungs are clear . There is no focal consolidation or pneumothorax . There is no vascular congestion or pleural effusions . There is apparent mediastinal widening which is more than what would be expected despite the supine portable technique . Findings may reflect underlying adenopathy or mediastinal pathology , recommend dedicated PA and lateral chest radiograph for further evaluation when clinically stable . The cardiac silhouette is normal in size .
    OUTPUT:
    
1 . Standard position of endotracheal tube 4 .5 cm from the carina . 2 . Nasogastric tube within the stomach , though side port above the left hemidiaphragm , and advancement is recommended . 3 . Mediastinal widening , partly due to the AP technique though is concerning for underlying mediastinal pathology . Recommend dedicated PA and lateral chest radiographs or chest CT for further characterization .
