Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Cardiac silhouette size remains mildly enlarged . Persistent mild pulmonary edema is demonstrated , not substantially changed from the previous exam . Small bilateral pleural effusions appear new in the interval . Mediastinal contour is unchanged . While there is persistent patchy right basilar opacification , including a more peripheral wedge - shaped opacity in the right lower lobe , overall these findings have minimally improved in the interval , particularly within the right perihilar region . No pneumothorax is identified . Degenerative changes are again noted within the thoracic spine .
    OUTPUT:
    
1 . Mild pulmonary edema , similar to the previous exam , with new small bilateral pleural effusions . 2 . Persistent peripheral wedge - shaped opacity within the right lower lobe , potentially an area of infarction or persistent / continued infection . 3 . Other previously described multifocal airspace opacities within the right lung and left infrahilar region have improved , and may reflect areas of improving infection .
