Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Slightly increased right lower lobe opacity is noted with probable small right pleural effusion . Bilateral pleural thickening , greater on the right compared to the left appears increased since the prior exam . Increased opacity of the right compared to the left lung has otherwise not significantly changed from the prior exam . No pneumothorax . Stable cardiomediastinal silhouette . Stable osteopenia and prominent anterior osteophytes of the visualized thoracic spine .
    OUTPUT:
    
No significant interval improvement in right - sided opacity with perhaps increased right lower lobe opacity - could represent aspiration / pneumonia , but consideration of chest CT is recommended to further evaluate given lack of improvement .
