Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is a moderate right and small left pleural effusion . The heart is mildly enlarged . There is right perihilar opacity and bibasilar opacities , potentially atelectasis given adjacent effusions . Mild pulmonary vascular congestion is present without frank pulmonary edema . Mediastinal and hilar contours are otherwise normal . The aortic arch is calcified . There is no pneumothorax .
    OUTPUT:
    
1 . Moderate right and small left pleural effusions with mild pulmonary vascular congestion but no frank pulmonary edema . 2 . Right perihilar opacity could reflect pneumonia in the proper clinical setting . Nonspecific bibasilar opacities potentially atelectasis , however underlying infection is not excluded .
