Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Views are expiratory and therefore evaluation is limited . Exaggerated pulmonary vascularity may be secondary to low lung volumes , however , mild interstitial edema may be present . Evaluation of heart and mediastinal contours is difficult on this study . Aortic calcifications are seen . Bilateral lower lung opacities likely reflect atelectasis , though infection is not excluded . No pneumothorax is evident on this view .
    OUTPUT:

Findings and limitations discussed with ___ by Dr . ___ by telephone at 1 : 10 p .m . on ___ at the time of initial review of the study .
