    INPUT: CARDIOMEDIASTINAL CONTOURS ARE STABLE COMPARED TO PRIOR CT SCANS , AND ARE AGAIN REMARKABLE FOR A LARGE HIATAL HERNIA GROUND - GLASS AND CONSOLIDATIVE OPACITIES IN THE LEFT JUXTA HILAR REGION ( CORRESPONDING TO THE LEFT UPPER LOBE AND SUPERIOR SEGMENT LEFT LOWER LOBE ) APPEAR SIMILAR TO THE RECENT CT . OTHER MORE SUBTLE GROUND - GLASS OPACITIES AS SMALL NODULES ON THE PRIOR CT ARE LIKELY BELOW THE RESOLUTION OF CONVENTIONAL CHEST RADIOGRAPHS . POSTRADIATION CHANGES AT RIGHT APEX APPEAR UNCHANGED . FOCAL LINEAR SCAR OR ATELECTASIS IN THE LEFT LOWER LOBE POSTERIORLY IS UNCHANGED . SMALL PLEURAL EFFUSIONS EVIDENT ON RECENT CT ARE NO LONGER VISIBLE .
    OUTPUT:
    
LEFT JUXTA HILAR OPACITIES ARE SIMILAR TO RECENT CHEST CT , BUT OTHER MORE SUBTLE GROUND - GLASS OPACITIES AND SMALL NODULES ON RECENT CT ARE LIKELY BELOW THE RESOLUTION OF CONVENTIONAL RADIOGRAPHS .
