Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart is not enlarged . The pulmonary hila , particularly on the left , are prominent , with a tapered appearance , similar to ___ . No evidence of CHF . Similar the prior study , there is evidence of volume loss on the right , with slight rightward shift of mediastinum and slight elevation of the right hemidiaphragm . Probable old rib deformities in the right upper zone , question posttraumatic or postsurgical . Developmental changes of the ribs are considered less likely . On the right , there is blunting of the right lateral costophrenic angle , possible slight pleural thickening and linear atelectasis or scarring in the mid zone , unchanged compared with ___ . There is equivocal increased in hazy opacity at the right base laterally , which may also relate to technical factors and / or pleural thickening . No discrete focal infiltrate and no consolidation is identified in the right lung . No posterior pleural effusions are seen . On the left , no focal infiltrate or effusion . Possible minimal atelectasis at the left base medially . At the edge of these images , a left hip shoulder arthroplasty is partially imaged , with evidence for a mid left humeral fracture which is probably healed . .
    OUTPUT:
    
Cardiomediastinal silhouette and right hemithorax volume loss are unchanged compared with ___ and ___ as is blunting of the right lateral costophrenic angle , subtle changes along the right chest wall , and right mid zone linear atelectasis or scarring . Equivocal slight interval increase in opacity at the right lung base , question due to interval increase in pleural thickening versus technical differences . No discrete focal infiltrate . No consolidation . No other pleural fluid or thickening . Possible minimal atelectasis at left base medially . Deformity of ribs at the right lung apex , again noted , unchanged over multiple prior imaging studies .
