    INPUT: Single supine portable view of the chest was obtained . There is a right internal jugular central venous catheter terminating in the low SVC without findings to suggest pneumothorax . Relatively low lung volumes . The cardiac and mediastinal silhouettes are stable . There is right basilar and right perihilar linear opacities which may be due to atelectasis / scarring . Additionally , there is also linear left basilar opacity , consistent with atelectasis / scarring . There is a chronic deformity of the proximal right humerus , not optimally evaluated on this study .
    OUTPUT:
    
Right internal jugular central venous catheter terminates in the low SVC without evidence of pneumothorax . Low lung volumes and areas of minor linear atelectasis / scarring .
