    INPUT: Lung volumes are low . This slightly limits assessment of the lung bases . The heart size is top normal . The aorta is mildly unfolded . The pulmonary vascularity is not engorged . Minimal streaky opacities in the lung bases likely reflect atelectasis . No pleural effusion or pneumothorax is present . There are no acute osseous abnormalities .
    OUTPUT:
    
Low lung volumes with mild bibasilar atelectasis . No evidence of pulmonary edema .
