    INPUT: Low lung volumes account for bronchovascular crowding ; however mild fluid overload would be difficult to exclude . No focal opacities are identified . Cardiac size is in the upper limits of normal . There is no pleural effusion or pneumothorax . A new right IJ line ends in the lower SVC / cavoatrial junction .
    OUTPUT:
    
Increased vascular markings may be due to mild fluid overload although assessment is limited due to low lung volumes . New right IJ line ends in the lower SVC / cavoatrial junction .
