Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart is mildly enlarged . The mediastinal and hilar contours appear similar . There is a moderate interstitial abnormality suggestive of pulmonary edema . Superimposed are more confluent opacities in the right lower lung , as well as a vague left upper lung opacity , probably within the lingula . A small - to - moderate pleural effusion is suspected with suspected loculation on the left . A small right pleural effusion may be present . New dense calcifications project over the mid mediastinum and appear to refer to the lower part of the sternum , which shows more irregular calcified appearance , than before , including suggestion of anterior increased soft tissue density .
    OUTPUT:
    
1 . Findings most consistent with mild - to - moderate pulmonary edema . 2 . Focal opacities in the right lower and left upper lungs , which may represent superimposed pneumonia , but are non-specific . Short - term follow - up radiographs are recommended , preferably with PA and lateral technique , if possible , in order to reassess . 3 . Small - to - moderate loculated left - sided pleural effusion . 4 . New calcification projecting over the central chest that may refer to the sternum . Correlation with physical findings and clinical history is recommended .
