Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lungs demonstrate a basal predominant interstitial opacity which could reflect underlying emphysema or interstitial lung disease without acute focal consolidation to suggest pneumonia . There is no pleural effusion or pneumothorax . The heart is mildly enlarged with normal cardiomediastinal contours . Sternal wires and surgical clips are compatible with prior CABG . The dual - lead pacemaker is also noted . Endplate concavity in mid thoracic vertebral bodies is seen at multiple levels and likely reflects age - indeterminate compression fractures .
    OUTPUT:
    
1 . No acute intrathoracic process . 2 . Compression fractures in the thoracic spine of uncertain chronicity and correlation with exam findings is recommended .
