    INPUT: Stable , moderate cardiomegaly . Mild distention of the azygos vein suggests mild volume overload . Unchanged , mild pulmonary vascular congestion without evidence of pulmonary edema . Linear densities at the left base reflect subsegmental atelectasis . Small region of nodular opacification at the right base is unchanged and may reflect the bronchiolar nodularity seen on the recent abdominal and pelvic CT from ___ and possibly a component of the remotely aspirated barium seen on both the abdominal and pelvic CT from ___ and prior CT chest from ___ . No evidence of free intraperitoneal air , but evaluation is severely limited by semi erect positioning . Recommend repeat upright or left lateral decubitus radiographs for more adequate assessment .
    OUTPUT:
    
1 . No evidence of free intraperitoneal air , but evaluation is severely limited by semi erect positioning . Recommend repeat upright or left lateral decubitus radiographs for more adequate assessment . 2 . Stable , bronchiolar nodularity at the right base .
