    INPUT: Frontal radiographs of the chest were acquired . The endotracheal tube ends 6 .8 cm above the level of the carina , slightly high . A left subclavian central venous catheter ends in the mid SVC . An enteric catheter courses below the level of the diaphragm and out of the field of view inferiorly . Heterogeneous opacities at the right lung base are slightly increased , consistent with aspiration pneumonitis versus infection . Left retrocardiac atelectasis is not significantly changed . Heterogenous opacities along the lateral aspect of the left lower lung are concerning for pneumonia or aspiration pneumonitis . The heart size is normal . The mediastinal contours are normal . There are no pleural effusions . No pneumothorax is seen .
    OUTPUT:
    
1 . Slight increase in heterogeneous right lower lung lobe opacity , in keeping with suspected aspiration pneumonitis versus infection . Similar appearing opacities along the lateral aspect of the left lower lobe , possibly aspiration pneumonitis versus pneumonia . 2 . Unchanged left retrocardiac atelectasis . 3 . High positioning of the endotracheal tube . Recommend advancing by 1 - cm .
