Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lungs are well expanded . Bibasilar ill - defined opacities are present , more conspicuous in the right lower lung in a paramediastinal location , with mild peribronchovascular thickening in these areas . There is no pleural effusion or pneumothorax . The cardiomediastinal and hilar contours are grossly unremarkable , allowing for slight high positioning of the aortic knob , unchanged , and probable scattered atherosclerotic calcification . Note is made of an old healed left posterior rib fracture and ? old healed right ___ rib fx . No obvious acute rib fxs detected on these lung technique films . A right - sided IJ line ends in the right atrium , approximately 5 cm below the cavoatrial junction .
    OUTPUT:
    
1 . Bibasilar opacities , right worse than left , suggestive of pneumonia versus aspiration . 2 . IJ line ends in the right atrium . Withdrawal of approximately 5 cm is recommended for placement in the lower superior vena cava . 3 . No gross pleural effusion identified . A small effusion might not be apparent on this view .
