Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are low . Cardiac , mediastinal and hilar contours are unremarkable . Minimal atherosclerotic calcifications are demonstrated at the aortic knob . Pulmonary vasculature is not engorged . Linear opacities within the right lung base and left mid lung field likely reflect areas of subsegmental atelectasis . Elevation of the right hemidiaphragm is chronic . There is no focal consolidation , pleural effusion or pneumothorax . Degenerative changes are seen within both glenohumeral and acromioclavicular joints , more pronounced on the right , with narrowing of the right acromiohumeral interval suggestive of rotator cuff disease .
    OUTPUT:
    
Bibasilar atelectasis and chronic elevation of the right hemidiaphragm .
