    INPUT: The heart size is difficult to assess due to the presence of bibasilar airspace opacities , possibly reflecting atelectasis though aspiration or infection are not excluded . There are bilateral pleural effusions , small on the left and moderate on the right , with mild pulmonary edema noted . The mediastinal contours are unchanged . There is no pneumothorax . Diffuse demineralization of the osseous structures is present with mild loss of height of several thoracic vertebral bodies , similar compared to the previous exam .
    OUTPUT:
    
Mild congestive heart failure with small to moderate sized bilateral pleural effusions , right greater than left . Bibasilar airspace opacities could reflect compressive atelectasis but infection or aspiration can not be excluded .
