Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Endotracheal tube terminates approximately 7 cm from the carina . Right - sided Port - A - Cath tip terminates in the mid SVC . Low lung volumes are present . Heart size appears moderately enlarged . The aortic knob is distinct with atherosclerotic calcifications noted . Widening of the superior mediastinal contour may be reflect underlying lymphadenopathy . Patchy and linear opacities in the lung bases likely reflect areas of atelectasis . There may be a small right pleural effusion , though no large pneumothorax is identified on this supine exam . No displaced fracture is visualized .
    OUTPUT:
    
1 . Low lung volumes with bibasilar patchy and linear opacities , likely atelectasis . Please note that aspiration or infection can not be excluded . Possible trace right pleural effusion . 2 . Endotracheal tube in standard position . 3 . Widened superior mediastinal contour suspicious for mediastinal lymphadenopathy .
