Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Mild cardiomegaly with left ventricular predominance is re - demonstrated . The aorta remains tortuous . Right hilar lymphadenopathy is unchanged . Mild increased interstitial opacities may suggest mild pulmonary vascular engorgement or shronic interstitial abnormality , similar to the previous study suggestive of mild interstitial edema . Lungs remain hyperinflated compatible with underlying emphysema . Linear opacities in the lung bases likely reflect areas of subsegmental atelectasis . No new focal consolidation , pleural effusion or pneumothorax is present . Moderate multilevel degenerative changes are seen in the thoracic spine with anterior wedging of a vertebral body at the thoracolumbar junction , unchanged .
    OUTPUT:
    
Mild increased interstitial opacities appear chronic and may reflect mild interstitial pulmonary edema or chronic interstitial abnormality , unchanged .
