    INPUT: The left IJ line projects slightly more distal , near the cavoatrial junction . Lines and tubes are otherwise grossly unchanged . No pneumothorax detected . Again seen are extensive patchy opacities in both lungs , most pronounced in the right upper and mid zones but also seen at the right and left bases and left perihilar region . The overall distribution is similar . Changes in the right upper and suprahilar zones may be slightly less dense . No gross effusion . Cardiomediastinal silhouette unchanged . Prominence of the main pulmonary artery is again noted .
    OUTPUT:
