Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is a patchy opacity in the right lower lung , but dramatically decreased since the prior radiographs and perhaps a residual area of minor scarring associated with earlier infection . Streaky opacities at the left base are minor and probably due to minor atelectasis . There is no pleural effusion or pneumothorax . The cardiac , mediastinal and hilar contours appear unchanged . Mild - to - moderate rightward convex curvature is centered along the lower thoracic spine .
    OUTPUT:
    
Minimal basilar opacities , but probably due to atelectasis or scarring with no convincing evidence for pneumonia .
