    INPUT: The study is limited due to the patient 's chin projecting over and obscuring the apices as well as patient rotation . Within these limitations , heart size is likely top normal . The aorta is tortuous and diffusely calcified . The hilar contours are grossly unremarkable . Patchy right basilar opacity is poorly assessed on this exam , but may reflect an area of infection or atelectasis . No pleural effusion or large pneumothorax is identified . No displaced fractures are seen , but please note that assessment of the right - sided ribs is limited .
    OUTPUT:
    
Limited exam . Patchy right basilar opacity may reflect atelectasis or infection . No displaced rib fractures seen , but assessment of the right - sided ribs is limited on this study . Please note that a dedicated rib series can be obtained for further assessment .
