Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The frontal and lateral radiographs of the chest were acquired . Midline sternotomy wires are intact . Surgical clips are noted throughout the left hemithorax . Round opacities projecting over the area of the aortic root are thought to represent coronary artery markers . There is a diffuse interstitial abnormality that is more prominent in the lower lungs , possibly at least partially attributable to mild - to - moderate interstitial pulmonary edema . There is no focal consolidation . The heart is mildly enlarged . The mediastinal contours are normal . There are no pleural effusions . No pneumothorax is seen . The bones are probably demineralized .
    OUTPUT:
    
1 . Diffuse interstitial opacities with a bilateral lower lobe predominance , thought to be at least partially attributable to mild - to - moderate interstitial pulmonary edema . A coinciding underlying interstitial abnormality could be considered as well , however . Correlation with any prior imaging is recommended to assess the degree of change from the patient 's baseline . Although doubted , an atypical infectious process can not be completely excluded to explain a widespread interstitial abnormality . 2 . Mild cardiomegaly .
