Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The cardiac , mediastinal and hilar contours appear unchanged . There is better aeration at the left lung base with decreased streaky left posterior basilar opacities . Patchy right basilar opacity has increased slightly , but is highly non-specific and probably compatible with atelectasis . There is no definite pleural effusion or pneumothorax . The chest is hyperinflated . Bones appear demineralized . A severe mid thoracic compression deformity appears unchanged . Milder lower thoracic compression deformities are also probably unchanged , although better depicted on this study . Left - sided rib fractures appear old and non-displaced .
    OUTPUT:
    
1 . Increased patchy right basilar opacity , which could be seen with atelectasis . Aspiration or pneumonia are not completely excluded , however . Short - term followup radiographs may be helpful to re-evaluate if needed clinically . 2 . Improved left basilar aeration . 3 . Stable compression deformities , mild to moderate rightward convex thoracolumbar curvature , and left - sided rib fractures , which appear old .
