Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Moderate enlargement of the cardiac silhouette is unchanged . The aorta is diffusely calcified and tortuous . Mediastinal contours are persistently wide , but relatively stable . There is mild pulmonary vascular engorgement and mild peribronchial cuffing , but no overt pulmonary edema . Minimal blunting of the costophrenic angles is noted bilaterally . Linear opacities in the lung bases are compatible with atelectasis . No pneumothorax is identified . There are mild degenerative changes in the thoracic spine . Cervical spinal fusion hardware is partially imaged .
    OUTPUT:
    
1 . Bibasilar atelectasis and trace bilateral pleural effusions . 2 . Mild pulmonary vascular engorgement . 3 . Persistent mediastinal widening for which correlation with CT is recommended .
