Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Single frontal view of the chest demonstrates an ET tube ending 5 .6 cm above the carina . An enteric tube traverses inferiorly out of view with side port below the GE junction . A left subclavian approach Port - A - Cath has tip terminating in the lower SVC . The heart is prominent . The lungs are mildly hyperinflated , consistent with known emphysema . There is increased hazy opacities in the left upper lung , which likely represents asymmetric edema , versus consolidation . There is also right upper upper lung opacity , raising question of consolidation . There is also subsegmental volume loss in the lower lung zones . Previously seen right lower lobe consolidation has improved .
    OUTPUT:
    
1 . Appropriate ET tube positioning . 2 . Prominent cardiac contour and increased left greater than right upper lung opacification , likely representing cardiac decompensation and asymmetric edema . 3 . Ca n't exclude supervening infection in the upper lungs . Consider reevaluation following treatment for pulmonary edema . Improving right lower lobe consolidation . 4 . Severe emphysema , basal predominant , in keeping with known Alpha - 1 antitrypsin deficiency .
