Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There has been interval placement of an endotracheal tube , terminating approximately 6 .2 cm above the level of the carina . The lungs remain hyperinflated . There has been interval development of patchy opacity at the left lung base which may be due to atelectasis or aspiration , giving short - term interval . Patchy lateral right apical opacity is again seen , more prominent as compared to chest radiograph from ___ , and while could theoretically be related to scarring , given patient is underlying emphysema and COPD and again , nonemergent chest CT recommended to further assess . Right infrahilar opacity may relate to confluence of vascular structures although consolidation underlying pulmonary nodule not excluded . Slight blunting of the left costophrenic angle . Mediastinal contours are stable . Hilar contours are stable . Cardiac silhouette is top - normal .
    OUTPUT:
    
Endotracheal tube terminates 6 .2 cm above the Carina . Interval development of patchy left basilar opacity , may be due to atelectasis or aspiration given short - term interval . Patchy lateral right apical opacity again seen , more prominent as compared to chest radiograph from ___ , and while could theoretically be related to scarring , given patient is underlying emphysema and COPD and again , nonemergent chest CT recommended to further assess . Right infrahilar opacity may relate to confluence of vascular structures although consolidation or underlying pulmonary nodule not excluded .
