Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are low . Heart size is mildly enlarged , and likely accentuated due to the presence of low lung volumes . The aorta remains tortuous . There is crowding of the bronchovascular structures with mild pulmonary edema . Small bilateral pleural effusions are present , more pronounced on the right . Bibasilar opacities likely reflect compressive atelectasis . No pneumothorax is present though assessment of the lung apices is obscured by the patient 's neck soft tissues projecting over these regions .
    OUTPUT:
    
Mild pulmonary edema and small bilateral pleural effusions . Bibasilar opacities , likely atelectasis , though infection can not be completely excluded .
