    INPUT: Frontal and lateral radiographs of the chest were acquired . Lung volumes are slightly low . Streaky opacities at the right lung base are likely secondary to atelectasis , although early infection in this region can not be excluded . The lungs are otherwise clear . There is pulmonary vascular congestion without frank interstitial edema . Moderate cardiomegaly is noted . Mediastinal contours are normal . There are no pleural effusions . No pneumothorax is seen . Multilevel degenerative changes of the thoracolumbar spine are noted .
    OUTPUT:
