    INPUT: Single AP view of the chest provided . An ET tube ends 2 .0 cm above the Carina . An orogastric tube extends below the level of the diaphragm , the distal tip is not visualized . A left PICC ends at the distal SVC . Retrocardiac and left basilar consolidation is unchanged . There is suggestion of a mild leftward shift of mediastinal structures , however this may be due to rotation . No pleural effusion or pneumothorax . Hilar contours are normal .
    OUTPUT:
    
Retrocardiac and left basilar opacity are unchanged . Additionally , there is suggestion of a mild leftward shift of mediastinal structures , however this may be due to rotation . A nonobliqued image may be useful to assess whether the retrocardiac and left basilar opacities are due to volume loss or possibly pneumonia .
