Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Low lung volumes persist in the patient is somewhat rotated . Elevation of the right hemidiaphragm persist . Right base opacity could be due to atelectasis although consolidation , potentially due to infection or aspiration , is not excluded in the appropriate clinical setting . No large pleural effusion or pneumothorax is seen . The cardiac and mediastinal silhouettes are not well assessed due to the low lung volumes although mediastinal contours are unremarkable and similar to prior . . Chronic deformity at the right shoulder is re - demonstrated . The study is suboptimal for the assessment of rib fractures .
    OUTPUT:
    
Persistent low lung volumes and elevation of the right hemidiaphragm . Right base opacity could be due to atelectasis or consolidation . Study limited for the assessment of rib fractures . If there is clinical concern for such , CT is more sensitive and should be considered .
