    INPUT: Lung volumes remain low , accentuating the cardiac silhouette and bronchovascular structures . There is increased opacity at the right upper lung which could be related to prominence of the azygos fissure and azygous vein due to increased venous pressures . However , in the appropriate clinical setting , these findings could also be related to aspiration . In addition , there is an increased area of opacity along the right perihilar region and right lung base which could be related to atelectatic changes .
