Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: An endotracheal tube terminates 1 .9 cm from the carina with distension of the mid trachea suggesting mild hyperinflation of endotracheal tube balloon . An enteric tube courses below the diaphragm outside of the field of view . A coronary stent projects heart . Mild central pulmonary vascular congestion is associated with mild interstitial pulmonary edema . Left retrocardiac opacification likely represents a combination of effusion and compressive atelectasis . A faint nodular opacity in the left upper lung adjacent to a rounded structure external to the patient is likely due to overlapping densities of the ribs at this level . Attention on followup is recommended . There is no pneumothorax . The osseous structures and upper abdomen are unremarkable . Dense calcification of the aortic arch is noted .
    OUTPUT:
    
1 . Retrocardiac opacification is likely a combination of pleural effusion and compressive atelectasis . Superimposed consolidation is possible in the proper clinical setting . 2 . Endotracheal tube terminates 1 .9 cm the carina with apparent mild overinflation of the endotracheal balloon . 3 . Mild central pulmonary vascular congestion mild associated interstitial edema .
