    INPUT: Portable semi-erect chest radiograph ___ at 10 :42 is submitted .
    OUTPUT:
    
A feeding tube is seen coursing below the diaphragm with the tip not identified . Surgical clips in the right upper lobe with an associated predominately linear opacity are again seen likely reflecting postoperative changes with scarring . A left hilar clip was also again seen . Increasing areas of patchy opacity in both lung bases more likely reflect atelectasis , although an infectious process can not be entirely excluded . Clinical correlation is recommended . No large effusions . No pneumothorax . Overall cardiac and mediastinal contours are unchanged .
