Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lordotic and supine positioning . Lung volumes are slightly low , resulting in bronchovascular crowding and bibasilar atelectasis . Possible background hyperinflation / COPD . The mediastinum is prominent and there is also cardiomegaly , likely accentuated by low lung volumes and lordotic positioning . The aorta appears tortuous . The hila are likely prominent , with a somewhat tapered appearance . There is upper zone redistribution and vas and slight vascular engorgement . Small bilateral effusions would be difficult to exclude be some pleural thickening along the inner surface of the right chest wall . The differential diagnosis could include subpleural soft tissue related to body habitus . Doubt pneumothorax or focal consolidation .
    OUTPUT:
    
1 . Low lung volumes and lordotic , supine positioning . 2 . Possible background hyperinflation / COPD . 3 . Enlarged cardiomediastinal silhouette with tortuous aorta . This is likely accentuated by technical factors as well as body habitus . Clinical correlation requested . 4 . Mild vascular engorgement without overt CHF . 5 . Possible pleural thickening along the right chest wall --___ could be sequela of remote trauma or relate to body habitus . 6 . Small effusions would be difficult to exclude .
