    INPUT: The heart size is normal . The hilar and mediastinal contours are within normal limits . Linear bibasilar opacities most compatible with atelectasis in the setting of low lung volumes . The central pulmonary vessels are engorged , and hazy peripheral interstitial opacities likely reflect trace edema . There are trace bilateral pleural effusions . No pneumothorax or focal consolidation is seen .
    OUTPUT:
