Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lungs are hypoinflated with crowding of vasculature and bibasilar atelectasis . Subtle increased right upper lobe opacity . Mild vascular congestion has improved . Small retrocardiac opacity is stable . No pleural effusion or pneumothorax . The heart is top - normal in size , decreased since prior examination and likely accentuated due to low lung volumes . Mediastinal contour and hila are unremarkable . Interval removal of endotracheal tube and enteric feeding tube . Right IJ CVL tip is in the low SVC with left IJ CVL tip in the SVC junction .
    OUTPUT:
    
1 . Subtle increased right upper lobe opacity may represent atelectasis or early pneumonia in the appropriate clinical setting . 2 . Persistently hypoinflated lungs with bibasilar and retrocardiac opacity . 3 . Top - normal heart size , decreased since prior examination . 4 . Improved mild vascular congestion . 5 . Right IJ CVL tip in low SVC , left IJ CVL tip in SVC junction .
