Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There are low lung volumes and patient is rotated somewhat to the right . The aorta is tortuous / unfolded with slight increase in prominence of the ascending aorta which may be due to differences in patient position . There is minimal interstitial edema , possibly slightly improved since the prior study . No definite focal consolidation . No large pleural effusion although a trace right pleural effusion is difficult to exclude . The cardiac silhouette remains enlarged . No pneumothorax seen .
    OUTPUT:
    
Tortuous aorta . The ascending aorta is slightly more prominent as compared to the prior study although this could relate to differences in patient position / technique . If concern for acute aortic process , chest CT is more sensitive . Minimal interstitial edema .
