Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart size is normal . Mediastinal and hilar contours are unremarkable . There is no pulmonary edema . The right hemidiaphragm remains elevated . Focal opacity along the peripheral aspect of the right lung base is more pronounced compared to the prior radiograph from ___ , but correlated to an area of rounded atelectasis on the prior radiograph and CT from ___ , and may relate to atelectasis / scarring which is accentuated by the decreased lung volumes . This is adjacent to remote right rib fractures . Left lung is clear . No pleural effusion or pneumothorax is seen . Degenerative changes are noted in both glenohumeral joints . Multiple clips are again seen in the left upper quadrant of the abdomen .
    OUTPUT:
    
Focal opacity within the periphery of the right lung base , which could reflect atelectasis / scarring as this was an area that previously showed rounded atelectasis in ___ , but is more pronounced compared to prior chest radiograph from ___ , likely due to reduced lung volumes . Recommend short interval follow up radiographs with improved inspiratory effort for further assessment .
