    INPUT: Compared to the prior film , the ET tube and NG tube have been removed . The right IJ central line remains present , similar in position . Inspiratory volumes are improved and the cardiomediastinal silhouette appears significantly smaller . Elevated left hemidiaphragm remains present . Previously seen dense retrocardiac opacity has improved , with residual patchy opacity still present . Minimal patchy opacity in the right cardiophrenic region is new question atelectasis , but attention to this area on followup films is requested . No gross effusion . The extreme inferior right costophrenic angle is excluded from the film . Mild vascular plethora could be accounted for low inspiratory volumes . Old healed fractures of the left fifth , sixth and seventh ribs again noted .
    OUTPUT:
    
Interval removal of ET tube and NG tube . Considerable interval improvement in previously seen retrocardiac opacity , though residual patchy opacity remains present . New small right cardiomediastinal patchy opacity -? Atelectasis , although attention to this area on followup films is requested to exclude a focus of aspiration pneumonitis or an infectious pneumonic infiltrate .
