    INPUT: In comparison to the last chest radiograph performed several hours ago on the same date , there has been interval placement of an OG tube . It is seen extending distally to at least the mid / lower stomach , where it crosses the inferior margin of the image . The endotracheal tube is unchanged in position . A tubular structure with a distal coil is seen in the right side of the neck . There is a wedge - shaped opacity in the right upper lobe , which is new since today 's CXR but was noted on today 's CT scan . It likely represents pulmonary infarction in the setting of known pulmonary embolism , but can not exclude superimposed aspiration . There are no large pleural effusions or pneumothorax . The cardiomediastinal silhouette is unremarkable . No acute osseous abnormalities .
    OUTPUT:
    
1 . OG tube terminates in at least the mid / lower stomach . 2 . Wedge - shaped opacity in the right upper lobe , likely infarction from pulmonary embolism . However , can not rule out aspiration in the appropriate clinical setting .
