Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: An endotracheal tube has been placed since the prior examination , which terminates 3 cm above the carina . An orogastric tube courses towards the stomach . It s tip not visualized . The sidehole , however , appears to lie slightly above the left hemidiaphragm . Superimposed on background elevation of the right hemidiaphragm , there is persistent opacification at the right lung base with right infrahilar opacification and suspected pleural effusion . Aeration is much better in the left lower lung , however , which appears better expanded with reduction in opacification . There is no pneumothorax . Mild congestion appears similar to slightly decreased with enlarged indistinct vessels .
    OUTPUT:
    
1 . Status post endotracheal tube placement ; sidehole of orogastric tube projecting above the gastroesophageal junction . The clinician was aware of the finding and the tube had apparently been replaced by the time of interpretation . 2 . Findings suggesting mild vascular congestion . 3 . Persistent right basilar opacification suggesting atelectasis associated with elevation of the right hemidiaphragm and suspected pleural effusion . 4 . Improved aeration of the left lung base .
