Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is persistent mild elevation of the left hemidiaphragm and bandlike atlectasis in the left lower lung . In comparison to the prior study however , there is improved overall aeration of the left lung . Persistent left perihilar opacities are in part due to pulmonary vascular crowding and atelectasis , though resolving contusion may also be a component . The right lung is clear . Cardiomediastinal silhouette is stable . There is no pleural effusion or pneumothorax . Multiple fractures involving the left ribcage , left mid shaft clavicle and the left scapula are better evaluated on recent CT . The endotracheal tube terminates 7 .5 cm above the carina and should be advanced by 2 cm for optimal placement . The enteric tube is curled in the stomach directed towards the fundus . Left chest tubes unchanged in position .
    OUTPUT:
    
1 . Endotracheal tube tip terminates 7 .5 cm above the carina , and should be advanced by 2 cm for more optimal placement . 2 . Improved aeration in the left lung with persistent opacities compatible with bronchovascular crowding and atelectasis , and possible resolving contusion .
